At least for now. Such changes are risky (we have very many packages),
and apparently it needs more testing/review without blocking other
changes.
This reverts the whole range 4d0e3984918^..8752c327377,
except for one commit that got reverted in 6f239d7309 already.
(that MR didn't even get its merge commit)
