Doesn't matter!
You still need to send a digital image from the id, signed by an authority, saying "this person is 18"
You then still need a trusted ID service or algorithm to capture an image of the user _at the time of use_ to compare that to.
Just having access to your digital ID credentials proves nothing
The zero knowledge proof only helps prevent tracking between the ID service and the website you're logging into. This is valuable but requires standardisation and client side support, which doesn't exist.
All the time the client side is implemented by JavaScript served from the server side you're just trusting these parties to behave and not snoop

Yeah...I'm fully aware what a ZKP is..you're just missing the point.
Why did you write that then:
