hallelujah! Did you ever get anywhere formulizing the manifesto? I want to support.

BTW: ammo for your cause.

It helps to understand that the people who created the Agile Manifesto predominantly worked in Enterprise development as consultants and the manifesto was their remedy for the problems that exist in that context. It was right on for that context. When they said "customer", they meant their customer, the middle/senior manager that hired them, or the business unit that they worked with. Not the end-consumer of the software.

The Enterprise development context is very very different than the Product company context, and the only commonality that they share is that they both write software - that's it. How, why, where, and what they do are all different and frankly the agile manifesto and scrum process is not actually fit for purpose in the product context, where, are you correctly point out, we care more about outcomes, discovery and experimentation and innovation.
