Enums and namespaces are the only runtime features of TypeScript.

So, yes, you can't just strip types, but it's close.

Is there a comprehensive list of such incompatibilities documented somewhere?

		That's not the same. That guarantees that the types do not determine the output (e.g. no const enums), not that you can "strip" types to get the same output.

Not that I'm aware of.

Decorators would be another example. (Though they have always been marked experimental.)

And of course JSX, but that's not a TypeScript invention.
