It being in the reference implementation instead of the spec is a massive difference. One means that it's just there to show an example, and we should push national governments to do it better in their implementations, while the other would mean that it'd be a requirement for all implementations, which it doesn't appear to be.
It also looks like the reference implementation removed that functionality entirely several months ago: https://github.com/eu-digital-identity-wallet/av-app-android...
Edit it was not visible from the discussion link but it is visible from the issue link below. Also it seems to be transferred over from a totally different repo?
