I'm against this. We should instead find a solution to allow FCCs/PFAs to work on constructors and new rather than adding static factories for every possible class in existence. I restarted work on a PR to clean up the semantics of constructors that, I believe, would make it feasible to allow FCCs/PFAs on new MyClass. [1] Best regards, Gina P.
