While the website fails frequently, it does know to properly implement these policies.
FWIW, this has also been my experience when using miles/PU503s to upgrade. SDC puts you into your ticketed class of service, which should reflect the ticket's status at its most recent point of (re)issue.
When there is a schedule change and a "YOU MAY MISS YOUR FLIGHT" message, a P fare ALWAYS allows me to select the front cabin on DL.COM. I was actually able to change that into a GREAT connection in ORD to ATL on VERY full flights, because (THANKFULLY), DL held V inventory until the gate. Swooped right in and got my F seat.
