I checked all the other default bridges and all of them but 2 are
publishing statistics:
C8CBDB2464FC9804A69531437BCF2BE31FDD2EE4  cymrubridge31
0BAC39417268B96B9F514E7F63FA6FBA1A788955  cymrubridge33
I will contact the operators and ask them to try setting
"AssumeReachable 1".

I suspect it has something to do with the Tor version number. Here are
the other default bridges and their version numbers. The only old one is
the last one, which is the one I had to set AssumeReachable on to get it
to show up.
