“Maybe later” doesn’t explicitly say that you’ll never get the prompts again, so even if it did work that way, PMs would be able to weasel out and change it back to nagging you with the next update. (In reality, the wording like that is used precisely for this reason already, and that’s why we hate it.)

And it doesn’t really help the user. If I click “Not now” and later decide that I do want the feature, how do I find it? If you want to reassure the user, just say that:

  Enable cool new feature X?

  (You can always change this in System Settings → Y.)
