It does. We're currently missing some bits in upstream systemd to resume properly, but Ubuntu have them in their initramfs implementation. This should be easily fixable. See Lennart's email in the other thread for more details.

So I'll be slightly curious if, with all the hibernation work Ubuntu is apparently doing, they end up going with partitions or if they've got some other trick up their sleeve, like teaching the bootloader how to find and resume hibernation from a file.
At least on Windows and macOS, the hibernation file is a separate thing from swapfiles. Maybe there's a good reason for this distinction, I'm not sure.
