What’s the deal with the really loud wheels when coasting?

It is sad that 20+ years of real world proof that high end cartridge bearing hubs are as reliable and robust as cup and cone hubs has duped people into thinking that high end cartridge bearing hubs are as reliable and robust as cup and cone hubs.
Just another example of people paying too much attention to real world results and not enough to conjecture and theoretical navel gazing.

The Spesh rear hub on my Tarmac SL6 is pretty loud: I should really take it apart and put some grease in there but I quite like the fact it alerts others to my presence, and its not as rude as a bell.

Didn't think so. Okay, everyone but Shimano can go back to the freehub drawing board.
Unless you're cool with starting with an inherent flaw for the sake of the manufacturer's convenience... But it'd be nice if you could just admit that.

Is designing for the straightest load path theoretical navel gazing?

Some engineers apparently determined that despite the issue you bring up, the bearing would still hold up fine. And time has proven them right.
You know what IS a flawed design? A hub that is trashed is someone drops the ball on the bearing maintenance. If you are a mechanic, you have surely seen this many, many times. The reality is that most people do not do the needed adjustments and maintenance on cup and cone hubs. A design which does not account for this real world fact is flawed, IMO.
You know what IS robust design? One that lets you replace the part that wears out. Though the reality (you know what actually happens in the real world) is for high end hubs that takes a looong time.

Campy deserves props for being the only mob I know of who ever bothered to supply replacement cups, illustrating that it's not inherently game over for a worn loose ball hub... Not that it should come to that, since the cone goes first, then the balls, at which point it should be pretty obvious something's up.
The problem with them requiring adjustment isn't really related to the user - the fact is, loose ball hubs generally come way too tight from the factory, and too many bike shops are happy to leave them that way so they can extol the benefits of a shiny new cartridge bearing wheelset when the customer comes back in a year or two with trashed cones.
If they're properly adjusted (which come on, is pretty easy to get right), most riders will never have a reason to touch them before a rim wears out. Sounds pretty damn robust to me, but capitalism.

Mavic wheels can be built around different model and different brand hubs. You want to find out what kind of hubs these particuular wheels have.
But honestly, from all your different posts and threads on this subject, I think you would be happier with something cheaper and lower end.

I don’t think the 350 was “upgraded” to the new EXP ratchet system (ie “Ratchet EXP 36”). It’s still on the old “Ratchet System 18” according to DT Swiss website. Only the 240 and 180 hubs were changed to the new system. So, yeah, the 350s should be nice and quiet.

The 370 was upgraded from 3 pawl to 18T star ratchet.

Loud hubs save lives!
OK, seriously; Back about 1997, I bought a new wheel with a Phil Wood hub. It was the loudest freehub I'd had ever heard. It sounded like a one-pound bumblebee hovering near my rear hub when coasting.
Fast forward ~12 years. It began making a horrible new noise when coasting, so I sent it in to Phil Wood for an overhaul. When I got it back it was silent. I mean dead silent!
I was so curious that I called them up to ask what had been changed/upgraded. Their answer:
"We just replaced the worn-out parts and packed it full of grease. Nothing was changed."

I have loud and quiet hubs. I find i coast longer with the louder hubs that I own. I can quiet them down with grease but it slows them down so I use chainsaw oil (it’s tacky and sticks well to metal) and enjoy the sound of speed

I don't want to have a hub that is so loud if my bike is not that crazy expensive. lolz
I mean.. I see lot of people buying cheap chinese loud hub to make their bike crazy loud. Just me... I prefer a quiet bike unless I have a TDF bike capable.

I was inspired by this thread to pack some more grease into the hubs of the Zipp 404s that I bought used last year. I never liked the "angry bee" sound of the rear hub, and on this evening's ride they sounded normal. How long will this normalcy last? Dunno. Fingers crossed!

Resigned myself to the swarm of angry bees. Not happy about it though

Some hubs aren't ''grease packable'' however. DT Swiss, for instance, says that putting too much special grease will result in faulty engagement. Did mine recently and it was clearly indicated in the instructions. Not sure how much you can actually put before having pwoblems though!
