Unfortunately, when the supporters of the merged-/usr-via-aliased-dirs
pushed their approach into the distribution, that meant that package
stopped being able to ship compatibility symlinks under «/», and those
needed to be "handled" in maintscripts (by reimplementing poorly and
unsafely what dpkg is supposed to do). This means dpkg is not in the
loop and cannot perform a safe upgrade moving these pathnames safely,
as long as merged-/usr-via-aliased-dirs is supported.
This is all kinds of nasty, because a proposal that has a complete
disregard for the packaging system, and is founded on assumptions
about features that do not even exist, is also forcing that design
breakage into a solution that would otherwise require no such hacks.

No. Even if today we magically could get all .debs shipping object
directly under «/usr» instead of «/», and had the aliased symlinks in
place, the problems I've mentioned would pretty much be in place.
