Ah, this link just turned on the light.  I can add this to setup.cfg:

[easy_install]
allow_hosts: None

It's moderately better than my previous take which was to set allow_hosts to
www.example.com.  Sounds like the best way forward is for us to recommend
adding this entry to prevent unwanted downloads.
