Clearly we have different needs. I've never needed to do any of those
things without stopping the system. In fact the "adding space" thing is
probably what looks most attractive, but I'm paranoid about disk failure
so I can't see myself ever expanding a filesystem across more than one
physical partition. I do realize that for a large multi-user
installation with RAID drives and whatnot LVM is the bee's knees, but on
my desktop I just make do with a judicious use of symlinks.

That's true independently of whether LVM is the default or not.
