That looks interesting - it does look like it takes some effort, and does lead to additional maintenance, but that tradeoff might be worth it for the right app.

Still, that's a stack extraction; which would work for something like an admin section, but maybe not so much for things more entwined? But then you have to adjust the component antytime you want to make a change...

I could see it working out. I Would be interested to hear of your results once you have an assessment of it as an approach.
