I don't know what the manual says, but vc-next-section's signature calls 
the prefix argument's value VERBOSE, and vc-register doesn't have a way 
to trigger backend-prompting either. So it might be difficult to add 
that feature in a backward-compatible manner.

vc-register doesn't work with C-u at all, though (shows an error), so it 
might be possible to do something in that area.
