Comment:

 #27841 was merged in the following version: tor-0.3.5.5-alpha. Meaning
 that 040, 041 and 042 all have the fix.

 #31549 makes it that dirauth will reject everything EOL and unsupported
 versions in the 035 series (LTS) that is <= `tor-0.3.5.6-rc`.

 The still maintained LTS 029 doesn't have HSv3 so this is not a problem,
 relays don't advertise `HSIntro=4`.

 So arma's statement is correct:

 > It might be that we have nothing to fix here, once we've bumped out all
 the obsolete relays from the network, and instead we should just keep in
 mind for the future that this situation is what protovers were meant for.

 arma: Is there any action items here or we can close this? (Unclear from
 the description if we need to change code?)

 We should definitely use this approach to reject still supported _buggy_
 versions in the future.
