But that's the whole point of LVM in the first place!

If you make a single PV, with a VG including it, you can carve it up and 
re-carve it up however you like, for whatever LVs you have or create in 
the future. You can even _shrink_ LVs and make the space available to 
other LVs, which you cannot do with partitions.
