How many times has a startup shown you the full cap table? Was this at the very early stage, before raising money, or even after funding rounds? The cap table contains names of individuals. Most founders I know were reluctant to share the exact details. At the same time it's impossible to value option or equity grants without knowing valuation estimates, shares outstanding, round sizes, and liquidation preferences. Those get shared more readily.
