Well I'd tell you that this already exists. It works well and drives a bunch of software in industries you've never heard of.
I'd also tell you not to do it because there's no money in selling tools to developers that makes developing easier, with fewer people. Indeed programmers are exactly not the target audience. The sweet spot is empowering one-man operations who find a niche and dominate it.
But you're right in one sense, all the value is in solving the edge case. All the grunt work is taken care of, so what's left is programming in the corners.
