Many OSes do not support it, because it is not unicast address space
(coming behind the multicast range 224.0.0.0/4).  Some do, but if you
put your webservers in there, you want to make sure that *all* clients
can use it.  So lots of software and hardware upgrades would be needed
to ensure it's actually useful.  And if you do that, why not do IPv6?

The other reason why this is not a useful avenue to purchase is that 
16 /8s would be burnt up in like 1.5 years time if we return to the
old regime of "show me your need, and I give you enough address space
for it" - many large providers could easily use up a few /12 here and
there... bang, first /8 gone.
