Looks like PSI based oom killing doesn't work without swap. Therefore
oomd can't be considered a universal solution. Quite a lot of
developers have workstations with quite a decent amount of RAM,
~64GiB, and do not use swap at all. Server baremetal are likewise
mixed, depending on workloads, and in cloud it's rare for swap to
exist.

We think earlyoom can be adjusted to work well for both the swap and
no swap use cases.
