I don't have cycles to support this development, but I do think that the
function is worth while, wether you are using a 3rd party IPAM model or
not, there are plenty of developers who expect a specific IP Address (even
if it was randomly assigned via some other process, like booting without
defining a fixed IP). This is what drives many in the whole "I must have
floating IPs, because I don't want to use DNS and expect to have _my own_
IP addresses to re-use" model for many users where that's not really the
best usage model (and causes all kinds of fun from a performance
perspective if you don't have hardware accelerated routing/NAT enabled).
I also agree that model #2 is the better idea, but model #1 would be very
