Even if you could do attribution correctly (I think you can do this partially if you are really diligent about A/B testing), that is still only one input to the equation. The other fact worth considering is the scale factor - if a team develops a widget which has some ARR value today, that same widget has a future ARR value that scales with more product adoption - no additional capital required to capture more marginal value. How do you quantify this? Because it is hard and recursive (knowing how valuable a feature will be in the future means knowing how many users you have in the future which depends on how valuable your features are as well as 100 other factors), we just factor this out and don't attempt to quantify things in dollars and euros.
