I'd argue that not only is JSX "like templates", it actually is a template. I know what the syntax sugar compiles down to, and I'm very appreciative of the benefits over traditional string-based templates. But for me the fundamental property of template is an easy way to interpolate data into a rendering structure, and JSX definitely is that. Perhaps you have a more restrictive idea of what constitutes a template?

I treat them as templates also in my mind. Don't see anything wrong with that. In which scenario do you think it doesn't work out well?

You could also argue that any template is syntactic sugar for whatever is happening behind the hoods.

Also if you do not treat it as a template, I'm concerned you will do something very hacky, unreadable and unmaintainable.
