@rcombs the proposal does talk about the DRM aspects of this, and tries to propose solutions that mitigate that issue. I don't know whether they're appropriate solutions or not, whether they go far enough or not, etc. I think that would be a healthy debate.
Saying "user agents shouldn't do that" is basically saying it's fine for millions of users every month to get their bank accounts stolen, their personal information sold on black markets, etc. -- unless you have a magic solution.
@delroth you're equating bots with, what, bruteforce attempts on user passwords? which is an extremely mitigable problem that's entirely solved by passkey usage
