I've not seen any mention of this anywhere and never saw it in previous versions of iOS (it may be old and apologies if so!):
Last night I was at a friend's house and they'd changed their WiFi password the previous week which I'd already updated, another friend was there and trying to connect but didn't have the new password, as he was asking them for it a notification came up on my screen saying "Aaron is trying to connect to this WiFi network, do you want to share the password with him?" and an option button to do so.
Very neat I thought!
