Interesting idea, but isn't that a violation of POLA? Imagine an
unsuspecting sysadmin trying to rm something, and forgetting
or not knowing about ~/.rm?

Isn't it better to protect important system directories with
something like:
  # chflags sunlink /path/to/dir
and unprotect them with
  # chflags nosunlink /path/to/dir
to avoid mistakes?

Thanks,
