Well, they sell meters that will do those things too. Admittedly, it's an add-on cost. But it's already there. And how smart do I really want this thing to be? I mean, the whole reason I do darkroom work is so that I do it. If I want the computer to do it, I might as well just do it in Photoshop.
For example, you could use the built-in camera to look at the enlarger output on the baseboard and from that, choose a printing grade and some dodge/burn suggestions (illustrated on the screen!) that will result in a fairly well-balanced print. The possibilities are hugely expanded.
