I think that would depend on what kind of changes releng@ would allow to
be in a pullup commit.

One idea is to commit my changes to the core DRM code soon, then just
add the lima and panfrost code as snapshots in a pullup to netbsd-10,
the full commit history for them would be in -current.

The ABI would have been fixed by the earlier core DRM changes.
