Definitely.

Yes, that happens frequently with filesystem labels, which is why I much
prefer LVM names.

Indeed, my VG names are always unique and descriptive.

The root partition is always called "root", which is why I was talking
about renaming the VGs rather the LVs.
Yes, it usually involves downtime for some other related reason, but
every time I've had to change a VG's name it would have been *much* more
convenient to do it while the system is up (e.g. would have shortened
the downtime and the administration time noticeably).
Renaming the root VG is really the only case where I find LVM names to
be a point of friction.
