Everyone who cast votes within the past few weeks is obviously still an active stakeholder
It's actually great counterexample to the claim that a lot of less active stakeholders "never" change their votes. When it is important enough, many will (though obviously not the ones who are dead, who lost their keys, etc.). Nearly all arguments about how often stakeholders are supposed to change their votes are being made by someone who doesn't like the decisions stakeholders make (including to be less active, change votes less often, etc.) and is trying to gain an advantage by changing the rules.
