JSX is a great syntax, and these changes mean nothing if you're a transpiler writer. What I was hoping for was the JSX transpiler that React uses would become flexible enough for any library to use, without the need to modify/rewrite the transpiler itself.
Yes it's possible for someone else to write something like this, but writing a compiler is no small feat =/

It's possible that this will eventually unify again. E.g. around a replacement for an object literal. E.g. a standard record type.
I don't care if JSX is this or that, I simply have no interest in using or learning it because its not significant enough nor applicable outside of your framework and enforces anyone else who I work with to also adopt it.
This isn't just my opinion, having discussed using React this was the general consensus in a team of very different people, I stated that its fine because you don'e need to use JSX ... but at the moment it looks like you are focusing on moving developers in the direction we don't want to go.

We intentionally don't specify semantics to give different transpilers the flexibility to compile the JSX into whatever's appropriate for the library you're using.
