Comment (by nickm):

 So, these two main questions from above still sit in my mind:
 > * Does it actually work to only start Tor when Tor receives a SocksPort
 or ControlPort request? When Tor first starts after significant downtime,
 it needs to download a pretty big amount of directory data, and build
 enough circuits for user traffic. Does that happen fast enough to answer
 the request that made systemd launch Tor?
 > * A Tor is _supposed_ to actually turn itself nearly off when it sees no
 user traffic. Does your need for this feature mean that feature is not
 working?

 I'm thinking that because of the latter point, it might be a better idea
 to work on #2149 than on this, since #2149 has more general applicability.
