josh's scheme only comes into play when there are two, competing
origination patterns. in this case the question is just which one to
agreed that we should be careful with anything that reduces the
ability of people to change routing dynamically. but let's remember:
that ability is already constrained by the fact that responsible
providers use prefix filters and require some kind of out-of-band
(IRR, letter, email) validation of prefix ownership. routing a new
prefix with a new origination pattern is not especially dynamic now,
so let's not worry about throwing out a baby that's not even in the
chief of operations & security
