Up until the release of bookworm, all Debian packages must be
constructed on the assumption that they _might_ be unpacked on a
system that has not yet been converted to merged /usr. Particularly
for priority-required packages, this means that no one will be moving
files from /bin, /lib, etc to /usr in the bookworm cycle.
Post-bookworm, if nothing changes, that assumption will no longer be
in force, and people who maintain packages that install files into /
will want to simplify their packaging by installing everything in /usr
instead. If they also want to change the binary packages that ships
some of those files at any point in the same release cycle -- kaboom.
