In what way is it a straw man argument? When rm was initially
developed, disk space and CPU cycles were at a premium. Keeping extra
files around to be garbage collected later was a waste of both
precious resources.

You're 100% correct that it hasn't evolved since the epoch, basically,
and I think it comes down to the old UNIX philosophy: do one thing and
do it well (with piped inputs/outputs where possible!). `rm` is mighty
handy at deleting files, so there's little reason to change it.

The "proper" answer was suggested up-thread: btrfs/ZFS with
lightweight snapshots allowing you to pull chute if necessary.
