Comment (by cypherpunks):

 Replying to [comment:3 teor]:
 > Also, our experience of research code is that it often needs significant
 work to be suitable for long-term use on millions of tor clients.

 That's very true. Luckily, the code is not ''too'' convoluted.

 > In particular, the "Eliminate path restrictions entirely" section of
 proposal 291 is relevant, because it conflicts with adding AS path
 restrictions:

 Wait, is this section advocating for allowing a single relay to be used as
 both a guard and exit in a single circuit? Or does it just mean that the
 second (unused) guard would be allowed to act as a middle or exit? Anyway,
 it would not necessarily conflict with that as it could be entirely
 optional and controlled by the configuration file (just like the use of a
 limited number of guards itself is technically optional).

 proposal. Then you can send it to the tor-dev mailing list, and ask for
 help improving it.

 That sounds like a good idea. I think I will consider doing that.
