    Could you , please , explain why ?

It's "just in case". It's not really required.
I prefer making sure every tool out there can read /boot partition
to avoid problems :)
pvgrub can't handle ext4 partitions, and does so in a non-obvious way
(often by just going into a spin loop...).
There are ext4 patches in various distro grub1 packages, such as those
which inspired the patch in 20652:c6ee21dca848 to pygrub/libfsimage.

I don't know how is it with pvgrub but pygrub is using libfsimage where ext2fs-lib subdirectory resides. If you're having e2fsprogs version that supports ext4 (should be available in Fedora 10 and higher AFAIK) you should have no problem with ext4 support there.
