It's exactly this, there is a group who come together and never agree on rules, but when they do, they never enforce them. It's I believe the definition of a paper tiger, sadly. A great idea executed horribly.
if they had a clear test that declares a site w3c compliant or not with no wiggle room then they could work with something like the ADA or other accessibility related standards and make w3c compliance required for ADA compliance.
So not at all? Shipping something in chrome isn’t enforcing a standard in my opinion. Enforcing a standard would be a regulatory thing, like having to use USB-C in certain situations.
Chrome is in a monopol position. If they decide to ship a new feature .. then all the other browsers need to implement it as well, or their users assume their browser is broken.
