This is the point of the "passkey" branding. The idea is to get to the point where these alphabet-soup acronyms are no longer exposed to normal users and instead they're just like "oh, I have to set up a passkey to log into this website", the way they currently understand having to set up a password.
Sure. That still doesn't make Yubikey-style physical devices (or desktop keyring systems that work the same way) viable for everyone, everywhere, though.
Yeah, the pressure needs to be put on vendors to accept passkeys everywhere (and to the extent that there are technical obstacles to this, they need to be aggressively remediated); we're not yet at the point where user education is the bottleneck.
