I think this list is missing some important user-visible properties, or it's
not clear which property above corresponds to these properties:

* Is Tor reliable and responsive when guards go down, or when I move
  networks, or when I have lost and regained service?

I also think it's missing an implicit property, which we should make explicit:

* Can Tor users be fingerprinted by their set of guards or directory guards?

Perhaps this property is out of scope.
