This is a very low stakes question but I just went to a bank to update my contact info (had business there already) and of course the extension letter wasn't accepted as a valid form of id.
Called for the manager, explained that it's formally accepted for I9, it's a federal thing etc, no dice. It's not something that will affect me at the moment but given that USCIS has no plans of giving people their plastic green cards I left a complaint to change guidelines and said this is going to become more and more common and the guidelines need to be changed.
Anything else that can be done/argued? If I was about to get a loan or something this would've been unpleasant to say the least. I had my GC, letter, passport.
