I agree. The primary officer at passport or customs control handles admissibility and makes the decision whether to refer to secondary, I do not think the electronic system would ever mandate automatic secondary.

That said, the primary officer has access to a lot of information, including automatically determined risk assessments, which they are not going to simply ignore. An officer can see past noncompliance (if it was noted) and decide you're not their job to deal with. And they have to keep the line moving...
