You can't move PVs. You need a separate /boot. If you use more than one 
disk then it adds significant fragility to the boot process. It slows 
down booting. It provides some functionality that's hugely useful in a 
small number of cases, and in every other case it just makes your life 
more complicated. btrfs does the former without anywhere near as much of 
the latter.
