/32s are *not* "big prefixes".

What are you aiming for?  

Reduce the ISP minimum allocation size - for what good?

If all the IPv6 space is handed out as /32s, we have 4 billion routes - which
is very bad.  Anything aiming for even smaller blocks (longer prefix) is 
going the wrong way - brings some benefit to conservation but hurts routing.

This suggestion is not useful.  If you reserve the rest of the /48, then
you can hand out the /48 in the first place, and be done with it.
