ETRTO rim widths, nonsense or any actual reasoning?

It has been noted by more than a few people that the ETRTO tire/rim
charts are heavily predisposed to mounting FAT tires on very skinny rims.

Some of us brave and daring souls have found that you get a much better
ride if you obtain a tire/rim combination where the rim is nearly (80%
or so) as wide as the tire.

There is a present trend of wider rims for wider tires, which both
works better aerodynamically (FWIW) and provides more stability for
cornering loads as shown here (from the article below):

I found this article quite enlightening:

Here's a fresh article on the widening of rims:

I've been using HED Ardennes 25SL wheels with 23mm tires for a few years
and like them. The difference in cornering is notable. And the lower
pressure (90 psi) is more comfortable on Québec roads.

A comment made to me on a recent club ride: "Do you have enough air in
your rear tire?? There's a little bulge at the bottom!"

My response: "There's _supposed_ to be a little bulge at the bottom!"

(The commenter weighs maybe 140 pounds and uses something over 120 psi.
He's probably never seen his tires deflect.)

He's probably lucky to see anything when riding on chip & seal - other
than the bills from his dental surgeon for replacing fillings!
