I have created an RFC here https://discourse.llvm.org/t/rfc-add-an-interface-for-top-level-container-operations/77807

Would it be okay to merge this pass as it is for now (there is already precedent in how fir.global is handled) and then fix everything together once a solution has been agreed upon?
