I really like that. It also helps reassuring the importance of items. Like, if you want to create the same story three times in a year, it might actually be important.
Wouldn’t a curated version of the icebox help notice that pattern early? Especially if the team changes quite fast.
It's that for a team of a given size, we can only collectively produce so much. So as long as we're always picking tickets of a priority that stakeholders and we deem of the highest priority, then we're doing the right things.
This necessarily means that the backlog probably grows.
