Funny, when I think about features, I picture code in my head. I remember picturing the code for cuppings when reading your post, which I wrote to handle raw beans (as well as blends and roasts), forgetting that I disallow that in actual usage. The reasons are simply to dissuade users from instinctively choosing a bean, when a roast is actually the better choice.
I can clearly see what you mean now, and how it would be helpful. I'll have a look at this, and see what code ramifications are involved in allowing cuppings of green beans. I can create an opt-in preference, to eliminate the chances of folks learning bad habits, but still allowing the functionality for situations where it can be very beneficial to have that reference.
