I’m convinced that Agents of SHIELD never was canon, but was just the next Multiverse over (like, Earth 617) where Coulsons survival was the divergent point, and things just gradually changed from that point on; so there’s no reason to suspect that the first season wasn’t just a “Just Off Screen” version of the movies, and everything after that got harder and harder to reconcile.
Agent Carter never had that problem, and all her contributions were secret because of the Patriarchy, so it’s still canon
