I'm sure you realize that that's a whole different discussion, which
will involve a monstrous amount of work, with questionable payoff.
(And definitely not doable *today* as TGSI supports tess, fp64, and
shader parameters, whereas nir supports none of those. Not to say that
it can't of course.)

I could make a similar comment that Intel should finally move its
driver to gallium and stop duplicating st/mesa and gallium/aux in meta
:)
