I'll refrain from commenting on just how braindead that is as an approach to 
security.  If there are cards out there that are configured that way (which 
I'm not disputing, although I haven't seen them), then it may be better not 
to have a default plugin by default.  Perhaps there could be a configuration 
option?

Agreed, there really isn't a good way.
