So, we are conservative with adding completely new components to the
main systemd repo these days, and prefer instead to add new stuff into
seperate projects under the "systemd" umbrella group on github. This
particularly applies to stuff that isn't necessarily at the core where
computing will go to, and quire frankly I have the suspicion that swap
partitions and suchlike are on their way out, and are not going to be
the default how future systems are set up.

Hence, yeah, we are happy to open up the github systemd umbrella
group, and add systemd-swap to it (well, if it follows our general
coding guidelines at least to some level, i.e. is written and C and so
on), but I am not sure this really belongs in the main systemd repo
itself.

I hope this makes sense?
