The hope when I was on the standard body was that norms would shift as technology enabled it to be shifted. That’s also the reason the ID can contain multiple records that attest various proofs while preserving privacy (eg a store age check for restricted items or bar age check wouldn’t get anything other than your photo and a statement that you’re over a certain age without revealing your name, birthday, etc)
Privacy is one nice benefit of the US Passport card, it doesn't have your address. Another big one is you can self-ID your gender so you can have a correct ID if your state makes it difficult or impossible to get a corrected driver's license.
In a physical context this needs a photo to be included in the proof too, right? So the instructions for the verifier includes matching the face with the actual person.
