I don't use hibernation on my laptop, but only sleep. It has 16GB RAM,
and 16GB swap would remove 33% of its overprovisioning to no purpose.
I have a tower with 14GB of RAM and that has ½GB swap which has never
been used, except when I borrowed it for /boot when trying out a fully
encrypted system.

I would have expected swap usage to drop dramatically when it
hibernates because you've got to have room for what's in memory,
compressed I grant you. Won't it drop a load of RAM caches that
it was holding onto?

True, but the alternative is running out of memory, and the OOM killer.
Obviously I don't know what you run that clogs the system. Most of my
machines have much less RAM than the two mentioned, though they get
less memory-intensive use nowadays. Maybe the difference is that
I don't install any DEs here.
