With kselftests we had the ability to only run a specified set of
tests, and with or without selection, we had sub-results for each
through dynamic subtests. Does kunit have that possibility? I mean I
know kunit itself does but what about igt_kunit()?

Orthogonal to that question, drm_mm and test-drm_modeset are _now_
using kunit but in LTS kernels they're not, and we'd like to be able
to keep testing those. That means having both launchers here and just
letting the "incorrect" one produce a 'skip'.
