I doubt modesetting will ever be mandatory on graphics cards that support
a text mode at all. (People have been saying that cards with no text mode
support are just around the corner for years, but I've never seen one
outside a Sun workstation.)

That is, of course, that I doubt that *kernel* modesetting will ever be
mandatory on cards with hardware text mode support, simply because all the
kernel needs to do to disable kernel modesetting on a particular card is
to do nothing. Breaking that would be pointless.

While that's true, at the very least it would mean no 3D acceleration, in some cases no acceleration at all.

Certainly on newer cards, yes. But, again, if you have a new card, you
probably have a new machine as well, and it's quite likely you *need* a
new kernel anyway. (And if you're changing the graphics card in an
existing machine, you can be assumed to be some variety of geek and thus
capable of building one.)
