I’m surprised the concept of drivespace/double space died off. Maybe most files self-compress well from their native app, but I’m sure it’s not universal. OSs don’t seem to offer a prompt to compress relatively unused files and transparently uncompressed them on-demand.

It did not, for example my /home is a btfrs mounted with compress=zstd:3

And some machines I’ve used, had swap on zram…
