Is an acknowledgement worth putting in a CV?
No. We don’t hire people to be our friends or to offer us emotional support, and I don’t even understand what “standing firm in support of the department’s goals” means. We hire them to teach, do research, and do other more or less well defined tasks, none of which are evidenced in any meaningful way by being mentioned in the acknowledgements to someone’s paper.

You can be the world’s most amazing, virtuous, supportive person, and that’s great, but no one will hire you for an academic job for those qualities. For your CV, focus on quantitative, measurable achievements that hiring institutions actually care about.
