Dunno, his argument makes sense.  And "generic variant" is all we
have for these cases until somebody creates an extension.  Maybe
4646bis should allow for future extensions deprecating variants.

Let's agree to disagree.  The info "Latn" should be implied by
these variants (fonipa, fonupa, pinyin).  Asking taggers to do
this "manually" is asking for trouble, some will, others won't.

Besides it would be massively redundant.  We have no decent way
to store the "Latn" info in the registry.  Comments don't help,
they are not for automatical processing.
