The developers suggested I try dracut and I do intend to do that.
My problem is, the one most likely affected by this is also the one I want to
experiment the least with. Guess I'll have to test this inside a VM.

The reason I ditched lilo when grub came out was because I always would forget
to run the lilo-command. (Another was that lilo wouldn't work on a new
machine, but that's not important)
The same will be true for dracut. And probably not just for me.
The on-disk-format may stay the same and the tools (am thinking LVM here)
should always be able to find my filesystems. But, what if the initramfs does
the fsck with older tools?
Currently, the fsck runs before actually mounting the filesystems. If the
filesystems end up being pre-mounted, when will fsck run and which version?
