Since you're talking of software RAID and LVM, that means you need an
initramfs to boot your system. Thus, your systems will continue to boot
with the proposed scenario, which supports booting with /usr on a
separate filesystem if you have an initramfs.

What exactly is the problem?

the following formula:
