If it wasn't global I'd probably be okay with it - but on our US routers 
at least it's a global setting and I believe gives some risk.

That's the problem - _I_ want to decide global policy for me - not 
someone else's route server.  I point to the discussion above and below 
you're making about trying to deaggregate to influence policy - clearly 
YOU also want to control global policy.
