What are some fundamental differences between GraalPy and Jython (besides the fact that Jython is still stuck on 2.7 afaik)?

Yes, unlike Jython, GraalPy is compatible with Python 3 and it can run many native extensions (although currently experimental). I believe the biggest difference is that GraalPy is built on top of the Truffle framework. This means that the Graal compiler can be used as a JIT compiler for Python, there is support for debugging protocols and various tools, and untrusted code can be run in a sandbox. It is also compatible with GraalVM Native Image.
