support for syntax plugins? #11165
Description
Describe the feature
As a test, the jsx stuff should be extracted to a syntax plugin since it's not JavaScript anyway (treesitter, for example, is clear about ecmascript being different from jsx (in highlighting queries anyway)).
This would make way for certain frontend frameworks to implement their own plugins (svelte, ember, angular, etc) for improved performance in these ecosystems with potentially multi-language ASTs.
