This can be dangerous behavior, or illegal behavior in the case of password fields or credit card information being retained (in JS, you can't backfill password fields, so I don't want my browser doing it with ephemerally cached info). I am fully willing to sacrifice something I don't use (and very few people rely on) over having to refill out a form or risk security to accommodate a very dated and almost unused behavior.
