Re: [webauthn] New platform authenticators are making discoverable credentials regardless of residentKey=false passed to Create() (#1457)

I don’t think that it’s clear whether or not Android stores a client side resident key. What is clear is that Chrome on Android doesn’t support assertion with an empty allowCredentials list. Subtle difference I know but an argument could be made that the create operation is still valid. In any case this is something the Google folks are best positioned to answer.
