FYI: I picked devcoredump because it was self-contained enough that I
could make a proof-of-concept and get the discussion started. I think
that, at least from this point of view, it has been successful, even if we
decide against a partial Rust driver! :)

I was informed early on that delaying a debugging feature until the
abstractions were merged would be a problem. Don’t worry: I can rewrite
the kernel part in C, that would indeed be a very small patch.
