Great post John, like you always do.
These product feature questions make complete sense and are really needed while defending a product roadmap.
Interestingly, these very answers will also be helpful when working with the Tech teams (my side of the world) when prioritization becomes a necessity. It gets really difficult to reorder work items when every request comes with a “high priority” tag. Taking a data based decision, like you mentioned, makes things easy for both PM and Tech teams.
