That is for registering that there at all are certain approved extensions.
It provides *no* data about the subtags "under" any extension.

The IANA language subtag registry has no way of registering what goes
"under" an extension. Only things preceding any extension (and separately
a list of approved singletons for extensions). Changing this would mean
revising BCP 47. That would be a major hurdle.

As Addison mentioned, one can have a separate registry for an extension that
is held by IANA. But that would mean defining lots of details on exactly
goes into the registry, its format, procedures for approval, etc. That is
NOT covered by BCP 47.

I can agree with that part.
