If it is the case that German IDs supporting selective disclosure aren't seeing adoption for services then it needs to looked at what the friction is or even just because it's optional. It doesn't necessarily have to be an ulterior motive. It'd be easy to be called out as conspiratorial otherwise.

Right now with age assurance laws and online services there has been no singular approach beside falling back to use of government ID that any country has required. Each country has just said 'here are the minimum criteria, choose what you want' and left it up to services to comply.

So what have services chosen? The least friction and cheapest existing solution to be compliant. For most services that's been using readily available facial scanning services and government IDs as fallback. Not all of them of course but it's so scattered that it makes it difficult for a person to know what they'll need for one service vs another (and perhaps even avoid use of a service if their approach doesn't align with the person's values).

Without mandating better minimum privacy criteria governments can just point to the fact they're not preventing such tech from being used and leave it at that. But solutions also need to be affordable to adopt for a wide range of sites/services and have good support (interfaces, etc) around them to catch on so it's not just entirely whether tech exists per se.
