jep[0] has existed for a while now, and does what GraalPy is doing quite well.

I'm using it for similar purposes as you stated and for that it works quite well. A research group I am collaborating with does a lot of their work in one Java application (ImageJ for microscopy), so by integrating my Python processing code into that application, it finds its way a lot quicker into the daily workflows of everyone in that group.

Most recently I've also extended the jep setup to include optional Python version bootstrapping via uv[1], so that I can be sure that the plugins I'm writing have the correct Python version available, without people having to install that manually on the machine.
