Android does this with zram, and I think this is a big part of the reason why it tends to use more battery once you run low on RAM, since paging in and out requires (de)compression, which uses CPU.
It'd be nice if they didn't break, but for example, since around OpenSSH 7.7, the order argument parsing changed from last wins to first wins. This change broke all of my aliases where I used to be able to have an alias sr="ssh -l root" and override the user with something such as "sr foo@host".
Last wins is how most other UNIX tools work, since it's the laziest approach (parse from first to last and just overwrite any old value). But I guess somebody tried to be explicit with the order of everything from the configuration file including the command line, and now this happened.
I really wish this would be reverted, but now it's probably been so long that it would break things for people again.
