Good points, helps solidify differences that I had trouble thinking about.

But to add, for me I wasn't talking about software, I actually engineered hardware- in my case, vehicle and airframe structures. Way more direct and less abstract than software. Large software systems may be some of the most difficult examples in the credit tracking problem, for sure.

My bad for assuming software. In your case, I imagine it's the lack of power law returns that make profit sharing less attractive.
