Sure. A couple of things to clarify:
1. They're not doing screening. The screening comes later. At this stage, they're attempting to identify someone. That has never been the job. The job is to prevent guns, knives, swollen batteries, or anything else that could be a safety threat during air travel.
2. Regardless, the reality is that they do identify travelers. Even so, the job has not changed. If you don't present sufficient identification, they will identify you through other mechanisms. The only thing the new dictate says is that they don't want this document, they want that document.

A job that by their own internal testing, they do well less than 5% of the time (some of their audits showed that 98% of fake/test guns that were sent through TSA got through checkpoints).
