A 26mm bar that weighs the same as a 31.8mm bar is most definitely more flexible, and IME they're noticeably more flexible unless they're steel or boat anchor thick-walled.
What's more, most 26mm bar/stem combos are flat out hanging onto each other landing off a gutter with your hands on the hoods; it's a totally undercooked spec. With 31.8, you can hammer it like that all day, no problem.
It deserves maximum pimpage; it's freaking sweet.

Like I said, boat anchor. A 220g ally bar is plenty stiff in 31.8, but sketchy in 26.
The simple fact is 26 is undercooked. How many times BITD have you seen bars that had rotated in the clamp? Quite a few, I bet. It was a spec born when bars were steel.

Aha, I still use 26.0 bars (from Schmolke, Syntace, 3ttt and Scott) combined with Syntace F99 and F139 stems I've never had any issues. Back in the day (I suppose he means the 1990's) we had to do with one-bolt clamps instead of the 4-bolt ones used by Syntace (which also have rubber inserts to further enhance friction between bars and stem).

But if it would appease all the Hot R' Not'ers, perhaps I'll just go find some super light bars and polish/paint the center section to match, build some ultralight wheels, and come up with some other goofy things I can do to cut weight off my mid-range 80's steel frame bike build

Hey, don't pick on my stem That Kalloy Uno stem is one of the lighter options out there. And the conversion headset saves a decent chunk of weight over the other options. Vittoria Corsa G+ tires aren't exactly heavy weights either. The wheels are on there until I build something better. Groupset was picked because of the black levers and brake calipers, and this was never intended to be a truly light bike, mostly a budget-friendly modernized classic frame. The handlebars are heavy, no doubt, but realistically I'm saving 50-60 grams using something else, spending a lot more, and I'd be stuck dealing with figuring out how to get a matching finish.

I was bearing the thread topic in mind with my digression; the idea being that form follows function, and that what works well should look good.
A four-arm crank is a good example; most of us appreciate the traditional aesthetic of a five-arm crank, and when Shimano ditched it, many of us found the new look tough to get used to. But the FC-9000 has definitely grown on me; part of my philosophy regarding such things is to actively integrate functional improvements into my ideas of what looks good. I'm not a fan of arbitrary styling; to my mind the form of a component should be completely dictated by functional considerations, with only the surface finish being an exception.
As such, I'm a fan of what Shimano is doing with anodising these days, and I hope they take it further... I'm not so keen on the odd little asymmetries and styling lines you see on their cranks though. Here's hoping for a less ugly future

How long is yours? Mine is 100mm and plenty stiff enough for steep hills and sprinting.

Those exist already. Two examples:
Velo Orange: https://velo-orange.com/products/qui...ceplate-31-8mm
Factory Five: https://wearefactoryfive.com/products/titan-stem
The latter is better but still fugly. Both are fairly expensive considering the short comings of each. The VO's angle is awful on a level top top tube frame but at least it comes in multiple lengths. I simply wouldn't trust that Factory Five stem being a full CNC'd part with a weak looking bar clamp design. And it is only available in 90mm length. Both are likely boat anchors. Neither allows for running the handlebars as low as my headset does.
With my headset design, you can pick any stem you like (length, angle, finish) and easily swap it out for something else should the need arise. And if the design is successful enough, what do you think the next item I plan on making is?

I considered the Factory 5, but it only comes in 1 length (80mm -too short), and the bulbous end looks wrong with a bar installed. If the top were flat and (with the "bulb" underneath) and came in longer lengths, it would be much more tempting.

The Factory 5 stem is dumb and goofy looking, and from what I hear, about as stiff as spaghetti.
