In part that's because I don't see other Raft implementations as competitors. A major goal in Raft was to enable many implementations. It'd be a huge fail if everyone switched to LogCabin and abandoned all the other Raft implementations.

Really though, it's probably not a feature list that'll make people want to use LogCabin. In Scale Computing's case, it's that they have a C++ code base that they could integrate LogCabin well with, and they know they can work with and maintain the code if they need to.
