Thanks, and I have good news on that front actually. I recently factored out a portable Scheme layer and got Jolt to compile against Gambit as a backend. And given that Racket is basically an extension of Chez, it should be trivial to build against it now.

I wrote up a post on how this works here https://yogthos.net/posts/2026-08-07-portable-jolt.html

Really cool, I see now that most all the the Racket extensions to Chez have been up-streamed which is positive for the health of both projects.
