They are training us to accept the inevitable ugly e-bikes. Same with the oversized downtubes.

Specialized call it their SWAT box: storage/water/air/tools. Newer models actually have a SWAT cavity in the downtube, no external box.

It looks ugly, but it works. I took it off originally but ended up mounting it back up on my Roubaix. It neatly holds a spare tube, CO2 cartridge and inflator head, multi-tool, and tire lever. Plus has space for a folded bill.
If people ask if it is a motor, I just say yes.

I do believe the Swat Box requires use of the Specialized tire levers. Can't have Pedros or others in there as they don't fit. In a seat pack I can put a cell phone, two tubes, Pedros tire levers, patch kit, C02 and a snack. Swat Box can't do that. Still need a saddle bag. What's the point other than another 50 bucks in their pocket?

Annoyed.
Personally, I'd welcome well designed and integrated storage built into the frame. Storage that handles a standard pair of tire levers, a tube, etc. The normal things you'd always want with you on a ride. A cell phone can still live in the pocket though.

Seems like the Trek method - removing large section of downtube - does what a convertible does to sports/muscle cars, e.g adds weight, reduces rigidity... which in turn means adding more weight to reinforce the area with the hole. I'll stick with jersey pockets.

But if you can all of those items in one jersey pocket, though... more power to you. Post a pic.. must be quite a bulge

The real reason is "aero."
UCI bikes aren't allowed to have fairings & what not, but are allowed to have a tool box. So it's a tool box that coincidentally has some aero benefit.
Some of the newer fancy aero bikes tend to test better in a wind tunnel with a pair of water bottles installed. Go figure.

I'm pretty sure UCI rules prohibit anything inside the main triangle except water bottles, and the shape of those is tightly controlled, The bottle on the Cervelo P4 is definitely not allowed.
