Well, "not worth" is too hard. One of the main benefits of LVM
is, that you can easily extend (and theoretically shrink)
filesystems. Since ext* can, in practicallity, only be resized
offline, one of the benefits goes away. Also, extending and
shrinking ext* takes *AGES*, as you MUST run "e2fsck -f $dev"
beforehand.

That's wrong. I suppose that those are your ext* fs?
If so, you can perfectly fine resize those fs while
they are offline.

No. Get rid of ext*. reiser3 and xfs are mature, use those
instead.
