The original behavior is as old as 4a5f38c4, and last time we talked
about that there were arguments about still keeping the existing
behavior to not cleanup files during a restart-after-crash scenario
for the sake of being useful just "in case". I have never used that
property myself, TBH, and I have seen much more cases of users caring
about the data folder not facing an ENOSPC particularly if they don't
use different partitions for pg_wal/ and the main data folder.
