That sometimes works, but sometimes doesn't: it relies on apt being
able to find a solution that its heuristics see as acceptable. In my
experience, having real transitional packages has always worked, so it's
a more robust route.

The upgrade to Debian 13 and Ubuntu 24.04 is going to include a lot of
Conflicts/Replaces as a result of the 64-bit time_t transition, so I think
anything we can do to reduce the number of packages being removed in the
upgrade path is likely to be helpful.
