OK, I bite.  What answer do you give to folks that need to renumber
things like site-to-site VPN endpoints, which affects lots of configuration 
to be changed by *other* folks (their VPN peers)?

This happens to be the one of the main issues being brought forward by
people that want stable addresses.

(I'll go through the draft itself some time tomorrow)
