 Replying to [ticket:25754 mikeperry]:
 >
 > At a high level, the choices are:
 >  0. Do nothing. (If we choose this, I want us to do it for specific
 reasons, rather than default to it).
 >  1. Use two guards, and ensure one is from a different /16 and node
 family (Section 1.1 and 1.2).
 >  2. Abandon all of Tor's path restrictions (Section 3.1)

 This '''"all of Tor's path restrictions"''' phrasing is scary. First of
 all, we only need to relax the path restrictions on HS-related circuits
 right (particularly HSDir, IP and RP circs)? And in particular we need to
 relax the single restriction of disallowing guard and final hop being the
 same node (or in the same family or /16). No other path restrictions
 should be edited IIUC.

 Example of bug that might become more prevalent if we reduce the size of
 primary guards: #25783

 Hello Mike,

 I did a big analysis of the engineering side of prop#291 here:
 https://lists.torproject.org/pipermail/tor-dev/2018-April/013057.html

 tl;dr Proposal will work well as currently written, but it can have some
 side-effects we might want to think more about.
