Default routes on BGP routers with full feeds

Long time I had the same opinion, however, if someone operates a network 
with multiple upstream providers the operator should be able to afford a 
proper out of band console access which solves this issue completely.

I would only accept a default route on Uplinks where I am only receiving 
a partial table for rescue purpose.
