Sure, but the question being asked is why should users of the daemon
process library need to worry about that, separately from other users
of lockfiles or mutexes?  If they need to worry about it only because
there's no satisfactory module implementing it widely available, then
that could be done in a subsidiary module that handles OS-specific
details, and optionally exposes OS-specific special features (a la os
and os.posix).  That would also make refactoring (close to) trivial
when such a module did become widely available.

It's obvious you don't want to go in that direction, which is IMHO
good and sufficient reason for you not to do so.  But as it stands IMO
it's a weakness in the PEP, even if Unix-only is otherwise acceptable
for the stdlib.
