Lvm has its backup data in /etc by default. If you ever need it you
are screwed with / on lvm. Also snapshots and pvmove don't work

raid0/5 don't have support in the bootloaders.

reiserfs/xfs miss support in bootloaders or their tail usage feature
breaks them.

Hardly anyone has it read-only nowadays.

Not all of those arguments work for everyone nor do they all work
together. Every user case is different.
