Sorry to intrude, may I ask what's the problem with language
injection? it seems the perfect use case for this.
According to Yuan this should already be supported with emacs (at
least the parser part, you would probably need to add some specific
rule for fontification).
Yuan, a complete example would be great!

Another use case in c-ts-mode would be fontifying format strings in
printf functions. There was some discussion about doing that in the Go
grammar and there too they concluded injections was the canonical
treesitter way for stuff like this and dropped the pull request.

Thanks,
