They'll be forced to renumber with /10. Using their own space, they 
could regionalize existing blocks, effectively doubling, tripling, 
quadrupling their existing allocated space. What is the complaint? That 
we must feed more than a single /10 netblock into the NAT444 device's 
config? The initial conversion blocks may require thought and planning, 
but once implemented, it should flow smoothly.

I've heard a lot of "but we can punish only some people with the /10 
allowing us to reuse our global space for more important areas where we 
won't punish people." Let's be honest. What we are saying is, give us a 
/10 to punish the cheap residential guys, so we can utilize all our 
other space for those who pay us money. Eyeball networks are the ones 
that can deploy NAT444 effectively, and I see no reason to give them 
more global address space, which they won't be handing back to ARIN for 
content providers to use (they'll just pad their own pockets with their 
side hosting businesses since they reclaimed millions of broadband IP's 
which are of high value).
