I am replying to you personally, and not forwarding it to the list, not
sure if that is correct netiquetee or not. Here is the a link to the
FAQ entry that discuss precisely the issue. Basically, the primary
developer disagrees with you.
I happen to agree with him, but that is because I end up using software
RAID and mirror everything and then build LVM devices out of them.
Technically there is not speed advantage for doing it for anything
except for RAID0 in the LVM. It causes a lot of code duplication
between the software RAID and the LVM.
A strong case could be made for a more GUI/command line capable disk
volume management that encompassed RAID/LVM/GFS/ext3/XFS/JFS/ReiserFS/nb
and every other thing under the sun to make administration easier, but
well, somebody will get to it, just not today.
