Most seem to be covered already by having records-with-methods. The only
issue is that it is a different kind of  "object".

I think if you want to pursue this, you must be much more concrete. Both the
benefits and the potential pitfalls.

This is patently false. Both Delphi and FPC are used professionally.

The dubious claim is the suggestion that detail language features are the
main cause for language uptake. It isn't.
