FWIW, site-locals were dropped (among others) due to concerns about 
sufficient guarantee of uniqueness.  ULA started by having only a 
local generation mechanism, no central allocation at all.  Would that 
allay your concerns?

I think we all know there's going to be _some_ form of PI space. 
Whether that's realized by making the policies weaker, by end-sites 
lying in their address applications, or end-sites providing 
interesting interpretation for "other organizations", or a number of 
different mechanisms, the fact is that some form of PI addressing is 
going to be there.  The question just is, what kind, how much of it, 
and to whom it's available.

The history also tells us that being too stingy when there is no need 
to be stingy will result in useless fragmentation of the addressing, 
and therefore results in the fragmentation of routing advertisements.

A minimum of /32 per ISP IMHO makes very much sense, because that's so 
small amount that we aren't going to run out.  On the other hand, I 
agree that one size does not fit all, and larger blocks will also need 
to be provided.  Oops, they already have!
