I was playing around with some thoughts.... for me the biggest problem
are per instance meta classes really.

Well, if I would make a suggestion to remove these or one of them, it
would have to be based on practical data. That is how the user is using
it, how it is understood, performance, maintainability and correctness.
Both features do not impose a big burden on method calls actually, so
performance is maybe not a problem. But we have to maintain a
complicated datastructure with possible memory leaks if you use per
instance meta classes on java classes. The usage is low and I am not
sure how many people realize the implications of using them.
