There's third-party code which relies on the current implementation.

Indeed, I'm among the culprits. :-)

I used to use (values ...)  instead of (list ...) to convey that the
first element is the primary return value, the other elements merely
auxiliary, and that more "return values" may be added in future. (So you
cannot use `destructuring-bind' on the returned list value.)

I considered the current implementation a quirk I regretfully took for
