As a practical matter, this causes Safari to TypeError if Enterprise attestation is requested.  

This is a real problem for releasing new features if relying parties need to check the version of the browser to see if it is safe to pass a particular value.

Perhaps having a way for the RP to discover if a specific feature/WebAuthn level is supported is the way to go but it moves even more work on to the RP and slows down adoption.

I noticed a similar thing with Github trying to use appidexclude and that breaking a browser for all make credentials.
