That's needed for more than just LVM (and probably won't go away, as it
is a lot simpler to handle a single method in the installer).

How does it do that (any more than any other multi-disk setup)?

Cite numbers? It was slower early on, but it goes right by now. I
don't doubt it adds some time (of course), but I don't see it being any
significant amount.

For most, it doesn't make things any more complicated (because they
never touch it). I'd say that LVM is useful in a growing number of
cases.

Oh, I don't object to btrfs and having the basic volume management in
the filesystem layer. AdvFS on DEC Unix was great in that respect. I
object to your painting of LVM aw "awful".
