@lostaccount, let’s not speak in generalities. What majors fit your description?
I am familiar with CS, where the bulk of “foundational courses” that typically transfer over from a CC either really are gen ed and don’t matter for success in CS or are built upon and do matter but are child’s play compared to advanced CS classes. In any case, the CS major GPA and grades in specific courses tells me what I need to know. Someone with a 3.8 GPA in CS classes and A’s in data strictures, algorithms, and OS isn’t going to have gaps in their foundational CS knowledge.
