actually, I have had an occasion (granted just one) where I had a really
large (4TB) LVM and added more drives to the system and created a new
'PV' but I joined them together as a single 'logical' volume. I believe
that is what you are referring to called 'spanning'.
It was a breeze and this was a server with RAID 10 so there's little
risk when you lose a drive.
LVM's provide a lot of added flexibility at the price of complexity.
