Facebook as the largest userbase of any application in existence. Its needs may not equate to your needs. For example, an enterprise b2b app with a few hundred customers could probably "deal with" the nuclear option.
The issue is I just logged in 90 seconds ago, typed up a few paragraphs, and when I go to submit I have to do it again, because someone in another company using the tool got phished and needs a new password.
It's frustrating enough when Gmail makes me put my password in after 30 days and I just clicked into an email I wanted to read. Having it happen all day long would make me want to kill someone.
