That's fair point which I both missed and not personally familiar with as I'm an Android user (Android's equivalent of Apple Wallet does require you to unlock your phone).
I still worry about relying on my phone to hold my ID and then surrendering my phone when it's reasonable for the other party (presumably a government entity) to want to look at it in more detail or take the ID away for a period of time (eg during a traffic stop they will take your ID to run you through the computer and write your ticket up)
I also worry functionality like this leads to changes in general expectations which leads to more implementation that may not be as carefully executed

There is no single equivalent, you are free to choose yours. PassAndroid is quite happy to show a pass on a locked phone, although you have to start the app first, but it's the best you can do in Android.
With Face ID, there's also the risk that a malicious viewer who is holding your phone could point it at you and get it fully unlocked before you are able to react. A cop who is standing at the window of your car would absolutely be close enough to do that. The only way this would be safe is if it engaged the emergency mode which requires the PIN/password to fully unlock.
I have children who like to play "unlock the phone" games, and we have tested quite a bit.
In my experience the cone is rather larger. Holding the phone and looking at the forearm or below it - which is easily 40 degrees off - will still unlock.
