Think of strategy for deprecating pluggable transports (e.g. obfs2)
Currently, most bridges (the 70%) run obfs3+obfs2 and the rest run only obfs2.
China has an active probing module for obfs2 and not for obfs3, so using obfs2 in China is bad currently. It doesn't allow you to bypass censorship and it might also burn the bridge (if they ever decide to do IP-based censorship and not IP/TCP-based censorship).
We should think of how to deprecate obfs2. A good starting point would be to completely remove it from obfsproxy (by removing the code) and also stop suggesting it via BridgeDB.
We should think if there are any problems with the above approach, and how we can improve it.
