At the risk of taking this thread further OT, I am a product manager / consulting CPO but a whole heartedly agree with you. I like the way you phrase it. A tool to evaluate progress and provide realistic completion dates. That is how I always push companies to use agile pointing and estimating. Use it to identify unrealistic roadmap expectations as early as possible, force hard conversations on priorities and staff allocation... before committing on plans to customers or stakeholders. Or when taking a risk on a delivery date, be doing that knowingly from the beginning, with contingency plans and management owning that risk and consequences otherwise.
