I *love* the idea of an conf.d/ style exit config.

I would very much like to see the default policy to be no-exit, because as I mentioned before I suspect we're losing some nodes started up by noobs who then get screamed at and just shut them down, without ever really becoming part of the community.  It needs to be as easy as possible to run a relay, and given that one *can* face legal consequences in some jurisdictions over what goes into and out of a computer one rents, no-exit should be the default.
