This is wrong, "UNICODE-1-1-UTF-8" was never in the IANA registry, which is
the reason I wrote up RFC 2044 in the first place: to get UTF-8 registered
as a legitimate charset.

Without guidance in the form of a proper registration, it is not surprising
that people have made the analogy between "UNICODE-1-1-UTF-7" (which has
been registered long ago) and "UNICODE-1-1-UTF-8" (non-existent).

The choice between "UNICODE-1-1-UTF-8" and "UTF-8" has been debated at
length on the ISO10646 and Unicode lists, with the result that we have now:
"UTF-8".  The wise implementer, however, would be well advised to support
the longer tag as an ad hoc alias.

Which is the correct status for a document supporting a charset
registration.  The authoritative references for the definition of the
encoding are given in the RFC, and the IANA registry is authoritative
regarding the charset tag.  The tag suggested in the RFC is only that, a
suggestion, but one that IANA has chosen to take in that particular case.
