It does work with GraalVM (although the last time I did anything with that, I went through Gluon, which provides a bunch of wrappers around it). I have no idea if Clojure works with GraalVM, but if it does I guess the only missing piece is doing all the work the Graal & Gluon Maven/Gradle plugins do in cljfx? Plus the multi-minute build cycle which requires several GB of RAM, but that's a whole different kettle of fish.
