Really? It seems impossible to me that a language that even thinks
it can guarantee that could interoperate with the backend's memory
management. And that's not something we are interested in replacing.

Yeah, that's what I thought. "Allow some parts to be written in
language X" soon turns into "Rewrite the entire system in language X,
including fundamental rethinking of memory management, error handling,
and some other things". That's pretty much a non-starter.
