We're in a thread talking about "standards first" things, and JSX just isn't a standard part of the web platform, nor is it in anyway standard within the ecosystem of JSX.

JSX has no semantics, only syntax. What a JSX expression means changes depending on the transform you use and the framework you use with it. Some JSX transforms produce values, some produce side-effects. Values produced with JSX under different transforms have different types and are not compatible with each other.

Maybe one day some form of JSX will be standardized, but until then tagged template literals work great with no tools and their behavior is fully determined by the template tag that you use, not an external transform. They're also more expressive than JSX (In Lit we support explicit attribute, property and event bindings rather than overload a single namespace for all 3).

Support for syntax highlighting, type-checking, and intellisense are available to IDEs via plugins and LSPs.
