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

it seems to be that me have a major problem of core package maintainers
coordinating features in Fedora.

See for example:

There the problem is, that dracut runs a fsck check before deciding
whether to resume. This can result in a big file system corruption,
since the kernel had a different idea of the file system state after
resuming from hibernation that there really is. The problem has several
core players that do not seem to communicate:

- dracut which uses systemd and showed this problem in F21 (I did not
  notice it in F20)
- systemd:
    - might have changed things in F21 to break resuming
    - Does only parse the kernel command line, does not parse the
      options that dracut gathers from the system during initramfs
    - provides hibernation support via "systemctl hibernate", which is
      also what pm-hibernate does (why do we have two tools for the same
      core task?)
- anaconda, which does not add a resume= kernel command line option when
  installing a system

Therefore please coordinate with others if you maintain a key component
for a core distribution feature and look for other items that need to be
