I think the end goal is to implement the jvm as a bytecode interpreter on top of truffle/graal and export it as a standalone executable via svm.

This also means that it will be easier to make vms with performance comparable to java.

One could, for example, design a functional bytecode and an svm based bytecode interpreter for it and write a language that compiles down to it to get a compiled language with a jitting (functional) vm!
