If you follow the user mailing list you would know that Bitsy have been upgraded to support TinkerPop 3.x.
https://github.com/lambdazen/bitsy/wiki At this point I'd say that Bitsy meets our listing policy, so I think we should add it to the provider index. I will assume lazy consensus in the next 72 hours (Sunday, December 17, 2017 7:00am EST) and proceed with the change unless there are some objections. Note that Pixy was also upgraded, but it's documentation is not yet in complete order. I'm told, however, that there is work underway in that department. We can consider Pixy when that gets settled.
