I wonder if it's just P quota, or glitches in the fare rules and booking engine?
A few times, I've had to pay $ to a travel agent to book me a P-class itinerary with AC on the intercontinental legs, and a *A partner airline on the other end. The AC web engine would only offer me the AC codeshare flight number, in economy. I needed an agent's help to book the leg under the operating carrier's flight number, in P (or equivalent). This was even when Expertflyer reported P>0 on the AC codeshare itself.
I've definitely had this with NH as the *A partner, and also at least one European airline -- can't remember if it was TP, OS, or LH.
