hibernation support - lack of distro-wide coordination between systemd, dracut, anaconda, pm-utils and maybe more?

What does this tell us? Fedora 21 uses systemd 216 according to the RPM
version. Does this already include all changes from 217? Why was a patch
for dracut necessary to get it work better? Is it supposed to run
without a resume= kernel parameter? If it needs one, then changes are
needed, because dracut stores the resume information in the initramfs
itself instead of using the kernel command line.

Do the pm-utils maintainers/upstream know this?
