The process could easily be automated, but there just isn't enough
demand to justify spending the time writing and testing code for it.

An expert would also find it pretty easy to test each step as they
proceeded without making any irreversible changes that risked data
loss.  E.g. using device-mapper to try out the device in advance
of the partition table change with the PV header sectors mapped 
somewhere else and using some of the advanced lvm.conf options 
that take metadata from elsewhere.
