I had a four pax itinerary with PRs applied for which I split myself out in the last minute. I was able to change myself into a future date online to preserve the PR.
That's a positive development.

The PR is the biggest reason you'd want it all on one PNR, but it's not the only reason.
In this case, the flights that were causing the pricing problem were all AC metal, so the $39 fee would not have applied. But I agree that could be a valid reason I'm other circumstances, as would wanting a round trip ticket for ability to change the whole thing in the event of a SKCH, and there might be other reasons to prefer one PNR as well.
I'm just pointing out one of the limitations.
