@eps1lon could we export JSX instead of making them global? This would make React play well with other JSX systems.

F.e., in one file that has a React component, and author would place this at the top:

/* @jsxImportSource react */

and then if they have another file with a different system, f.e. using Solid, they could write this at the top:

/* @jsxImportSource solid-js */

and then in the Solid component all the JSX types would be Solid-based JSX types where otherwise React types wouldn't make sense.

If someone only has one JSX system in their app, used in all their JSX files, they can place jsxImportSource in tsconfig.json so as not to have to write it in every .tsx file.
