I think it’s both that and the overwhelming reluctance to tell (and perhaps hire more) people carrying guns in an already safe and secure area to do (paper)work.

Similar issue in Canada where border officers allegedly do enforcement and provide services but want to focus on the “bad guy” enforcement part. Helping people out or sending bills to grandma wasn’t what they were promised when they signed up.
