Comment (by phw):

 Small update: My patch broke several unit tests because they rely on an
 obfs4 bridge being willing to hand out its vanilla descriptor. A proper
 fix will require a minor change to leekspin (the tool that creates test
 descriptors for BridgeDB as part of its unit tests), which I'm working on
 now.
