It is non-trivial to get additional ASNs, even if you are multi-homed
in multiple sites.
Doesn't mean it can't be done.
But AS exhaustion is far more critical than IP exhaustion. (Or even
RIB/FIB/proc exhaustion through additional prefixes, IMHO.) So if
they want to be .. uh, well, a good 'Netizen and use one AS with
static routes or defaults or something to route between them, that's
better than a slew of ASes with the same prefix info we have today.
