Yep! When I used to teach guitar, my "specialty" was ear training and theory. I encouraged my students to not think of modes as something derived from other (more well known) scales, but as separate entities, and no less important. I taught them to recognize their sounds by where the half steps (or in certain cases, the minor thirds) occur. And as it turned out, learning modes is a great way for guitar players to learn all of the "positions."
