I wasn't judging, I was explaining why the mechanisms in the current
policy don't work on real-world people - and as such, the policy is 
flawed in that respect.

(Yes, I see a difference between "startup LIR having problems in getting
an initial allocation -> fix policy" and "ccTLDs have problems in getting
ICANN to change glue records -> fix ICANN").

People actually do want PI space for other things (like "internal 
VPN connections that must be numbered unique but need not be routed").

But that's a different issue.

No, and that's part of the problem.  If it can be avoided in the first
place to have people announce multiple prefixes, then we should aim for
that.
