Good catch -- I've just started the process of getting the directory
authorities to un-recommend the 0.4.6 versions.

And you're right that it is a missed opportunity for those fingerprints
that started the process of getting bumped out a few days ago.

But (a) new relays that show up on 0.4.6, i.e. that don't have
fingerprints that are in the reject list, will see the warning about
versions,

and (b) I'm going to hold off on applying the big set of 0.4.6 reject
lines on moria1, so now moria1 should be issuing a warning about versions,
rather than a warning about a rejected fingerprint, to affected relays.

So at least in the case where the operator reads their logs well, they
should have some better idea what is up.

Thanks!
