I agree that there are problems with limiting this to a subset. But for the most part it’s a very good subset that mostly only removes features which would be rejected if proposed today, because they have runtime semantics. This would effectively deprecate those features in the real world. I’m in the minority who likes enums, but I can live without them. The real, big gap here is JSX. But that rightly should be a separate proposal. I just want them to consider it a prerequisite, to avoid fracturing that aspect of TS.
