Maybe there's no reason to fight over that, but I think this can be a
good idea. Are there any drawbacks of temporarily removing /usr/lib from
lib path before upgrading? In any case, this can help to make the
process work as expected by the developers.

I had recently such an experience with old GNUnet libs in /usr/local
that blocked it; not a big deal, but disabling them would have allowed
my update to go flawlessly. Many may be frightened by apt inconsistency
