[tor-relays] Previous Guard not getting Guard flag back

[Matthew Glennon]

Sorry - that was crass. Thanks for the attempt, but I've read those
documents. Specifically, I'm looking into what has changed, if anything. Is
it just below the threshold of the Weighted Uptime? (e.g. we have enough
Guards?) I asked because I was told that the bwauth issues were holding
people back before (because everyone was unmeasured). Since that was
resolved but still no guard flag, I was becoming curious.

I'll just sit back and wait some more.
