I have to disagree with you. I thought the same but if you look at the amount of traffic on forums and the Wiki pages as well as videos about it you can find absolutely every aspect of the framework.
Its all about putting time into research and usability. If you want something then research, ask questions, and contact community for help and JA are amazing when it comes to that part. Even helping with code if you are stuck, just check forums and see how many lines of custom code is in all of tge threads.
Its all about commitment to use something or not, people who just pass by allways are the ones who are too lazy to do some work.
Check out wiki, manual and videos then see how valid is your comment mate.
Cheers.
