Just wanted to add to your argument an inverse argument (for JSX, instead of against Vue):

JSX is actually just JavaScript with this one special rule:

    <foo bar={baz}>child1 {child2}</foo>

becomes

    transform("foo", { bar: baz, children: ["child1 ", child2] })

That's it. All the rules of JSX can be inferred from that one transformation.
