Why would you want to do that?
I've been tempted to do it the other way around, though. In a hosting
environment, you can end up with a bunch of /24s dumped on a
broadcast domain with a number of different customers but the
addresses so intermingled that you can't give each customer their own
VLAN. With IPv6, there is enough address space to give each customer
a VLAN and and address block to go along with that, which is a lot
cleaner.
