I think first we need to find a way to clean up signalled/exited/closed
processes in the elisp version of list-processes in order to keep its
documented behaviour.

Any objection to using this:

(mapc (lambda (p)
        (when (memq (process-status p) '(exit signal closed))
          (delete-process p)))
      (process-list))

This re-use delete-process instead of another primitive.

I attach an implementation of list-processes in elisp that's more or
less equivalent to the primitive list-processes except it no longer pops
up an empty buffer when the process list is empty.

Best wishes,
