That's not how it has always worked. Time to HUCA again.

SWMBO chose her Select Benefits in September, but the bonus points have not shown up for trips more than 30-days earlier. We'll call/write in when we have time.

EDIT: So, I decided to call in right away -- using the SE contact line for Aeroplan. The nice person there ("Ellie" at YVR) assured me that the Elite Status Bonus is still supposed to be retroactive, and she's put a request into the dedicated team they have for handling missing Elite Benefit credits.
