Dare I ask why not?

I'm not strictly opposed to this patch, but I think you're designing
something that isn't really what will be accepted upstream, the way I
see it you're thus painting yourself into a corner there and it'll
probably be hard to get out of it again.

I was actually thinking about this less from an address point of view
but more from explicitly enabling/disabling p2p etc.
