Of course Noel's given some thought to it. That's part of his job description: thinking about features that competitors do better and devising strategies to answer them.
But another part of his job is resource management. He doesn't work at Microsoft, doesn't have thousands of developers or a budget of billions. He's got to focus the company's efforts on those areas that are going to yield the best bang for the buck. A Reaper-style routing matrix just isn't a critical feature, merely a nice add-on that some users would find useful but most would ignore.
That said, I'd love to see it happen. It's the kind of geeky feature Cakewalk used to be known for, and that Noel & company probably secretly wish they could spend more time on. They'd do a killer job on it, I'm sure.
