It certainly feels dangerous if forced upon users not aware of the trade-offs. For people already accustomed to using hardware keys, it's very much an improvement, as more services will support them too. The problem is in the awareness. On the other hand, people already treat regular passwords as throwaway data and expect services to just let them in, or even never log them out. In this scenario, maybe passkeys can still be an improvement: roughly just as much as enforcing using a password manager.
