Who gets to choose? If it's the user, how do I as a user choose right now? If it's the service implementing passkeys, why wouldn't they force a solution that's easier for them (less testing/less support/less maintenance, by forcing attestation to a specific list of providers), instead of letting users have an option? Passkeys are an awesome solution to a difficult problem. But they are one bitflip away from eliminating user choice. Fix that problem, and I think folks here will jump on it in a hearbeat.
