The benefits of ext3/4 are irrelevant for /boot anyway - that
filesystem is write-seldom, read ever so slightly more often.
Really? I put my PC into power saving mode before going to bed each
evening. The PC needs to read /boot to return to normal operation.

Really. It takes maybe 1/4 of a second for it to load the kernel from
/boot. After that, it may not read /boot again until you boot back up
the next day. So, 1/4 of a second per boot is very little. The only
other time /boot is used is when you update grub or your kernel. That
is maybe a 1 or 2 second write, if that much. Even if you
hibernate/sleep/reboot a few times a day, it is still read very little.
That is pretty much irrelevant.
Me, I have always put ext2 on /boot. I just don't see much need in
anything fancy for something that is used so seldom plus everything is
likely stored somewhere else anyway. The kernel should be in the kernel
source directory and a emerge of grub would restore everything else
except the config. Not much to lose there.
