Correct: Provided you use the new "lvm2" metadata format, you're
limited only by disk space and the maximum device size that your kernel
will support.

That section now only applies to PVs in "lvm1" format.
It needs updating...
For tool performance reasons it's still a good idea to use large
physical extent sizes for large volume groups. (This will get
fixed eventually.)
