    I plan to propose a partial rewrite/refactor of the Python bindings later this year. This github issue collects up some of the problems I've noticed/identified and some associated PRs/issues

1. Decoupled/divorced lifetimes between C++/C/Python; succinctly this revolves around `liveOperations`
    - https://github.com/llvm/llvm-project/pull/93339
 - https://github.com/llvm/llvm-project/issues/69730
    - https://github.com/llvm/llvm-project/issues/92344
    - https://github.com/llvm/llvm-project/issues/93337
    - https://github.com/llvm/llvm-project/issues/63916
    - half-hearted attempt fix via removal: https://github.com/llvm/llvm-project/pull/92631
    - unfinished weak-ref system: https://github.com/llvm/llvm-project/pull/97340 
2. The CMake build system is "mysterious and important", which is to say it's abstruse and inflexible; succinctly this affects modularity vis-a-vis piecemeal dialect registration/distribution
