It's not easy to remove something once it's gone into an ISO standard,
I'm afraid. If you want to make it a long-term goal we can discuss it
in Amsterdam, though.

However, typed basenames will not be able to replace it entirely,
because variant names have a relationship to the individual base names
they belong to, because they are a variant of *that* base name, and
not some other base name. So throwing away variants does lose that
particular ability. Whether it's worth the complexity it entails is a
different issue, of course.

Yep, that's one of the benefits of a query language.
