two issues:

- I can't work out what the proposed new section 7 is saying.
- there are a bunch of problematic edge cases associated with section 5. 
E.g. what happens if an IXP has a /23 and has 254 IP addresses used 
after 1Y? They will be obliged to downgrade to a /24, according to the 
current text.  Also I don't know what a special circumstance is.

The problems in section 5 can be fixed easily, but it depends on how the 
authors want to handle assignment upgrades / renumberings. I'd suggest 
either dropping the 1Y utilisation requirement to e.g. 40%, or else that 
if you reach e.g. 80% current usage, you qualify to receive an 
assignment of 2x the current, up to /22.  Those figures are plucked out 
of the air btw. The point with them is that they are not 50%, which is 
obviously a magic number when the natural increase of assignment size 
would be to double the size of the block.
