Imagine this is a code library and I think it’ll become clear that while only uniqueness may be strictly necessary, inconsistent, undescriptive naming is harmful to API consumers, and to a lesser extent harmful to the implementers.

These are registrations, not documentation of independent usage, so yes, there’s somebody in charge, the IETF. They can enforce good naming, and do: https://datatracker.ietf.org/doc/html/rfc8615#section-3. They just apparently have either granted or grandfathered in many exceptions.
