It's not that easy for UTF-8.  We need the ugly scripts after
Unicode replaced the old charsets (the "implicit script" info
of most legacy charsets).  Where that's irrelevant you can of
course use language tags without script, the draft encourages
"taggers" that more is not always better, quite the contrary.

[...snipped...]  Yes, we calculated "the most perverse tag" in
all dimensions especially for 2231, I knew that you would kill
the draft otherwise... ;-)  Compare figure 7 in chapter 4.3.1.

Maybe you can convince the PTB to delay the "last call" until
the matching draft is ready, but I doubt it.  And I disagree
that it's impossible to judge the "data structure" (tags) now,
the syntax is rather simple.

For a general idea what the matching draft probably will be
you could read draft-ietf-ltru-matching-03.

Then let's agree to disagree and / or be more specific:  3934
is rather new, and it was used, all parts of it incl. appeal.

IMNSHO it would be desastrous to abuse RfC 3934 as some kind
of killfiling-by-rough-consensus.
