No it is not a pedantic difference.

If it isn't in a registry it didn't happen.

It is like when someone decided to do an April Fools RFC which used a code
point in PKIX space that wasn't actually registered with IANA. That caused
some real chaos.

Protocol matters. And just because IANA does 'assignments' that are not
'registrations' doesn't mean that is right or should continue.
