I didn't say anything at the time this idea first came up, because I
hoped people would understand that it was a bad idea.

Here's a little dirty secret about these tag characters: They were
placed in one of the astral planes explicitly to make sure they'd use 4
bytes per tag character, and thus quite a few bytes for any actual
complete tags. See https://tools.ietf.org/html/rfc2482 for details. Note
that RFC 2482 has been obsoleted by https://tools.ietf.org/html/rfc6082,
in parallel with a similar motion on the Unicode side.

These tag characters were born only to shoot down an even worse
proposal, https://tools.ietf.org/html/draft-ietf-acap-mlsf-01. For some
additional background, please see
https://tools.ietf.org/html/draft-ietf-acap-langtag-00.

The overall tag proposal had the desired effect: The original proposal
to hijack some unused bytes in UTF-8 was defeated, and the tags itself
were not actually used and therefore could be depreciated.

Bad ideas turn up once every 10 or 20 years. It usually takes some time
for some of the people to realize that they are bad ideas. But that
doesn't make them any better when they turn up again.
