Yet people still use it. Idk how many are new users and how many are using it with existing applications; but I am of the camp with those who don't use ORMs. Some people love them, and it's not usually the people that I expect. It's only failing 1 of 240 tests as I write this. I suspect something else will come out with class available in core now, anyway.
The point is, it's not just about "what other features does it need?"
I haven't gone through the list myself, but I have to suppose that at least some of the tickets are legit bugs.
So I can totally see the OP's concern.
