I do not understand why people waiting for PPR without waiting announcement from IRCC. I mean on their website they explicitly mentioned no passport request will be sent for now:
---------------‐-—-------------------------------------------------------
Permanent residence applications that we’re still processing
Some steps you may not be able to complete right now include:
submitting your passport or supporting documents, such as a police certificate
completing an immigration medical exam

So submitting the passport at this moment is not possible. Therefore, I do not understand how they can send PPR for outlanders.
That means they will continue to process the application till they finalize and ready to issue PPR. That's when they will park the application till submitting passport is allowed again.
