Any of the older DRI drivers that get dropped could easily be revived
later if someone wants to do the work.

I run a couple of machines with that driver and have to disagree with
that decision as well.

That would be me. I admit that because of personal/work reasons I've had
to keep myself somewhat out of the loop during the last couple of
months, that doesn't mean that I've disappeared or stopped answering my
mail.
Coincidentally nouveau's texture handling has always been structured
around two teximage map/unmap hooks (e.g. compare nouveau_teximage() and
the look of _mesa_store_teximage2d() after the API change), and AFAICT
the changes would be for the most part trivial, but still, if no-one
else wants or knows how to do it (isn't fixing up the drivers the
responsibility of whoever changes the API?), I'll get back to it as soon
as I can.
