Not when it crosses the drivers/staging/ boundry.

Either submit all of this stuff "properly", or put it in staging, don't
cross the boundry if at all possible, it just causes a lot of confusion
and headache as the staging stuff could be deleted at any time.

You still haven't explained why you feel drivers/staging/ is the right
place for this codebase.  Again, why not just submit it "properly"?
