Well that's a tricky one. I don't think there is a reasonable solution for
this problem.
In my opinion, the engine should allow adding parameters with
default values to the old API. In your example, we should just keep
the status quo. As I said before, I don't see a solution that "fits the
PHP goal". Such situations are certainly very rare and I can live that
restriction.
