I do see attestation as harmful. First, because it adds complexity that will make WebAuthn harder for website operators to implement. Second, because it creates a risk that websites will use whitelists of security key models, which will cause uncertainty among users about whether their security key will work on all websites.

I'll be elaborating on the problems with attestation when I release my easy WebAuthn library.
