It’s difficult to disentangle one from another, when the companies with the vested financial interest in locking you in are the board members of the consortium creating the standard.
Exactly. I'm disinclined to cut Apple, Google, and MS the benefit of doubt for steering a standards committee to spec + real world usage that privileges themselves.
The standard doesn't dictate the UX of settings screens. That's entirely on the platforms which own the screens and I would hope that is kept out of already-huge standards like WebAuthn.
