Comment (by andrea):

 This is going to end up just reporting how many active dirconns there are,
 I think; I've got the machinery to build lists of them for the download
 status queries, but the right approach to exposing more than a count is a
 way to provide a token usable with a more general connection-status query
 mechanism, and the existing control-port spec is pretty short on those.
 The only connection status query it seems to offer is /orconn-status to
 get a list of orconns.  If we care about this perhaps we should consider
 building a more general-purpose mechanism, but I think adding "<n>
 downloads active" satisfies the original intent of this ticket.
