There is also an interview (unfortunately in German, but automatically translated subtitles are available) with the minister who is responsible for the bill: https://www.youtube.com/watch?v=8Sm7Q1bjW5o
Asked by the interviewer if this isn't the same as asking bar owners to check the ID of every visitor just in case a bar fight breaks out, the minister answered:
"Das ist ja ein Blödsinn, was sie da reden"
(This is total nonsense you are talking about)
