Would they allow instance B to check instance A, and recursively?
Do we care about such a situation, one way or another?

To the points already stated in this discussion, I would add that we 
often recommend checking a "local document" to test any local 
installation. one recursion thus seems to be a good minimum for every 
installation, and, perhaps also a good maximum. I would lean toward 
making this a default, and at least hardcoded minimum.
