There are no plans to make dracut mandatory, unless you're putting root on
lvm or luks or something, and a good initramfs is already needed for that.
I think /etc/dracut.conf already has just about anything you'd want to be
persistent across runs.

Potentially - if the tools in the initramfs won't work. That seems unlikely
though - on-disk formats don't really change much and all stuff like mdadm
and lvm tools do is find stuff and pass it along to the kernel which does
the real work. If you migrate your root from raid1 to raid17 and the old
initramfs doesn't understand raid17 then you'll have a problem. I imagine
that if you migrate to raid17, however, you'd have put some thought into
this.

I suspect that if /usr is on raid1+lvm that you might need dracut. I'm not
100% sure on that, since in theory the initramfs can find all it needs on
root in this case. However, the goal was to keep it simple. I'd defer to
somebody actually involved with the simple image.
