Considering we're still trapped by the Gentle Tyranny of Call/Return, we'd probably choose the same interfaces...never mind the huge path-dependence on optimising all the parts around those interfaces. I have a sneaking suspicion that a more dataflow-oriented interface might be useful. The CPUs do dataflow analysis, the compiler does dataflow analysis, and higher levels are also often dataflow, but all communicate using a non-dataflow instruction stream. On the other hand, the only commercial dataflow CPU I am aware of, the NEC 7281 (http://www.merlintec.com/download/nec7281.pdf http://www.merlintec.com/download/nec7281.pdf) was less than successful.
