Oh, great to hear you are willing to take this. I know you must know much more about mangling than me. If you are going to refactor the mangling system, this one would be meaning less. I would abandon it later.

BTW, do you mind to be assigned for issue https://github.com/llvm/llvm-project/issues/52857 and https://github.com/llvm/llvm-project/issues/53232?
