I wouldn't be so sure, because they need to approve Students Visa so that respective candidates can travel once travel restrictions are lifted to join the universities. So they MAY focus exclusively on those visa which can sidetrack PR application.https://www.cicnews.com/2020/06/canada-resumes-visitor-visa-and-eta-processing-july-1-0614903.html#gs.93vxmt
I take this as a positive thing for us. If a student visa is getting processed, surely ours would get too.
Again these are my views and opinions. I don't intend to be negative or rain on someone hope but I believe that once all travel restrictions are lifted and atleast 50-60% of VAC are open IRCC would send out PPR to those waiting since March .
