I agree with that assessment. My experience has been reading a good bit into it. I considered learning it a few months ago, but wanted to focus on things that people were currently hiring for. Maybe at some point I will learn more, but I am a bit too broke right now to spend that much time on something that doesn't pay. I don't say that to be disparaging, it goes back to my point about it being immature and not having many engineers or companies using it.
