Once upon a time, UUNET did the opposite by setting

this might affect path selection.
This raises an interesting question we've dealt with many a
time in our network - outside of situations mandated by
governments or some such, are ISP's happy to peer with their
customers (where "peer" = settlement-free exchanging of
routes/traffic across public interconnects while "customers"
= servicing a commercial IP Transit contract)?
