Would a separate tag for Tor Controller be appropriate? I've only posted a couple of questions, but both were very much completely in the realm of Tor Controller (don't have the 150 rep to create the tag).
I hesitate to create this tag at the moment. When you search for question which contain the word "control", there are only a few which really deal with the control specification. Right the tag protocol seems to be a better fit. I added also this tag to your questions.
