Having used non-initramfs systems for years after it was recommended I
meanwhile switched to initramfs as you can embed quite a lot of useful
recovery tools with simple hooks so you can use them even when / and
/usr have issues, as long as /boot can boot into the initramfs.

Embedded systems without initramfs up to my experience handle stuff
differently anyways (and I haven't seen one installation with / and /usr
on different filesystems) and I therefore don't expect any impact on
those systems.

So far I haven't seen any convincing real world examples and I spent
some time looking. I'm curious as well if there are any corner cases
that would require adding hints to the release notes.
