I don't follow.

You cite three meaningful changes in biometrics: disfigured, loss of fingerprint and retinal issues.

In all three cases surely the right and proper thing do to is to get your details updated on the system ? It may even be a legal requirement for you to do so in the case of official ID documents.

Of course, if you have a temporary mismatch due to being injured on holiday that's different.

But for a permanent thing I just don't see why you would not just get stuff re-issued or updated.
