I guess people still do those. I have one on my laptop, but that's
because I only have 4GB of RAM in that thing. I'd never hibernate it,
though. If I can't just get it back from suspend immediately, I'd
rather just boot it from scratch.

On bigger machines where I have 16GB or more, I tend to go "I'd rather
fail early and perhaps buy more RAM than see the slowdown or write to
my precious ssd". I guess I might have a swap partition just because a
distro did one for me and I didn't catch it.

So yeah, maybe swap partitions are still more common than I thought.
And I didn't even consider the possibility that people would hibernate
a desktop like you do.
