The new routing system doesn't allow for arbitrary implicit dynamic tail path elements. (Basically, $args = func_get_args(); becomes useless in a controller/page callback.) There are currently no plans to fix that, as it is not particularly useful and is a slight security risk. A discussion to confirm that decision is up until Friday, in case there's some compelling reason we must spend time reimplementing that.
