You think that JSX would be suited for configuration files?

Why?

I don't understand your comment.

Because people reinvent half of it, different half every time in each project, and call it 'configuration' which somehow gives them licencia poetica for whatever crazy dung they come up with.

Compare ansible vs helm vs github actions vs literally anything with nontrivial config.

Note that if you asked me for real, I'd be a dhall proponent, but most normal people look at me funny the first time they hear it and then the second time they see the syntax.

dhall looks nice actually! Thanks for elaborating :)
