One reason for having /boot on a separate filesystem is to keep it safe. Some
distros (Gentoo, perhaps Debian?) default to a separate /boot filesystem
which is not mounted by default. This keeps your pesky users from mucking
with it. It also ensures that the /boot filesystem is never mounted
read-write during normal operations, including reboots. This pretty much
avoids the possibility of filesystem corruption. The only time you mount it
read-write is when you have to install a new kernel into it.
So a separate /boot is a safety measure.
