Technically that means I'd have to add a check for valid callback,
otherwise it'd risks oopsing if for whatever reason that's passed in as
NULL. It shouldn't be a problem in practice because it'll be valid in
all cases, at least until the unification patch, so perhaps there's no
need for the check if it's made optional in a subsequent patch anyway.
