Host it in a CPython instance and use through smth like rpyc.
IMO that's good enough if it's so critical to have that functionality.

After all, numpy is specifically designed for performance and memory-efficiency on large data sets.
Why even consider moving it to an IL environment infested with metadata and safety checks?
