What 3rd party password/passkey manager you use is not the business of a site unlike when they list allowed single sign-on OAuth vendors.. And using the managers is an alternative to using a secure enclave correctly. Monopolists will try to erode options and force everything on to their platform but if they didn't succeed with OAuth I don't see them being further ahead with warping the fido standards to be like it.
