that's quite encouraging.  one of the important things to bear in mind
and make clear: we always need to have the non-accelerated software-version
working, first, as an intermediary stepping-stone.  where that used to
be RISC-V RV64GC, it's now POWER9 (PowerISA v3.0B)

then on top of that, once that's stable, we can begin adding accelerated
3D / VPU opcodes.

so kinda by default we become the de-facto maintainers of the POWER9
version.  and consequently, yes, it's appropriate for that to be upstream.
