Once upon a time, UUNET did the opposite by setting origin to unknown for peer routes, in an attempt to prefer customer routes over peer routes. We moved to local preference shortly thereafter as it became clear this was "changing" the routes in some meaningful way; if a customer was multihomed to us and another provider, 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)?
