Replying to [comment:28 nickm]:
> Left a code review on github; I think this looks okay as a design,
though we need to make sure we don't actually give this output to any tor
authority versions that aren't running with #29806.
We'd really like to deploy this change in sbws, even if the authorities
haven't upgraded to a version of Tor with #29806. (Or even if we decide
not to backport #29806.)
I made some additions to the spec on the pull request, to explain why
that's ok:
{{{
Because Tor versions 0.3.4.11, 0.3.5.8, 0.4.0.2-alpha, and earlier
ignore this KeyValue, generator implementations MUST set "bw=1"
for a relay when Tor directory authorities SHOULD ignore its relay
line. Using the minimum bw value allows authorities that do not
understand "vote=0" or "unmeasured=1" to produce sensible votes
for unmeasured relays.
}}}
