An annoying and more complicated (but perhaps not less accurate) heuristic is that the revenue of the company is related to the sum of prior work. For a product company, the number of features drives use more than the rate of new features being added.

Under that model taken as-is there are some interesting features:

- The company could fire all the engineers and coast if the product is "done". Mostly reasonable, though products are never done.

- More "solve for the equilibrium", engineers are paid for the present value of their contributions rather than some proportion of current revenues. Depends on the company either being well-funded, paying in stock, or being able to take on debt. Again, rings true-ish? Hard to measure so obviously expected present value will differ greatly from the actual value.
