you _are_ able to do that (and have been able to do that
for some time now), the Feature just means that each guest
will get a fully isolated loopback IP

you need to assign the lback (loopback) IP to the guest
(which can be, and usually is, automated using the kernel
config option VSERVER_AUTO_LBACK), you also need to disable
the single ip specialcasing, if you are only assigning a
single IP to your guest, and finally, you need to make sure
that LBACK_REMAP and HIDE_LBACK is set (nflags)
note that this doesn't add or enable a 'loopback' interface
for the guest, it just isolates loopback traffic and of
course shows you the host's lo device
