There are performance benefits to the guest, of course, but (IMO) it 
doesn't justify spending resources pursuing it.  IMO.  Since you only get 
one V=R guest, it's not very interesting, PLUS it causes CP to dedicate 
real memory < 2GB to the guest, to the detriment of the other guests.

V=F/V=R is not supported in z/VM V5.
