Yes! I've actually tried it before but it seemed that the response rate
was quite low (even for commits that are obviously stable material) so I
turned it off to avoid spamming too much.

If you'd like to be the guinea pig for this, I could enable it for
drivers/gpu/drm/i915/ which I currently completely ignore. If at any
point you want it back off that's easy to do.

If this works well we can extend it to more subsystems where maintainers
might find it useful.
