Comment (by teor):

 Our security expectations of alternative tor implementations are pretty
 simple:
 * We do not expect alternative Tor implementations to be able to emulate C
 Tor's behaviour, so they are their own anonymity sets (there are several
 research papers on protocol emulation for anonymity: it doesn't work)
 * For this reason, and many others, alternative Tor implementations should
 not claim to support anonymity or privacy that is as good as Tor's:
 https://www.torproject.org/docs/trademark-faq.html.en

 So I'm not sure that writing a spec like this would be useful. A few
 sentences of threat model should be sufficient:

     stem.client does not make you anonymous. Use Tor Browser if you want
 to be anonymous. (Link to Tor Browser download page.)

 When we have a draft guide for embedding Tor in other browsers (like
 Firefox, Brave, or Cliqz), it might contain some useful information about
 threat models for alternative implementations.
