Thinking about it, I probably wouldn't remember to change my fingerprints to the new ones with all the services I use, I'd probably have to carry my "legacy fingerprints" wherever I go for some time to avoid a lockout.
These aren't really "credentials" in that they're not secret the way your iris/retina pattern, fingerprint pattern, password, pin, secret key, or security token are.
Your name, DoB, and email address are identifiers, yes, but aren't really authenticators - they're more like a username, not a password.
