Comment (by TvdW):
A while ago someone (I think arma/nickm) mentioned we should look into
whether we can simply disable Fast/Guard voting if an authority doesn't
have enough measurements yet.
After implementing this thought and testing it it turns out this may not
be a good idea: the network would lose all fast/guard flags if there are
insufficient bandwidth authorities. Also, Chutney would stop working.
I think this is better handled on a consensus method level, or we could
choose to get rid of the Fast flag completely and have the client
determine it instead.
In any case, I think having the authorities take data from a previous
consensus is not the correct solution to this problem.
