Please don't be so pessimistic. However, I feel the situation is quite sarcastic and unfair.
IRCC announced the required documents the day before the beginning of the application, and people rushed, resulted in mistakes.
Without the unrealistic schedule of the stream, most of people would not have to worry about their mistakes.
The schedule caused rushes which does not occur for EE, and it resulted in errors in documents.
Moreover, the 4 pillars to determine completeness was clearly disclosed only after people already submitted the application.
Further, on the application guide disclosed in April, they repeatedly explained that (only) documents for eligibility are mandatory on application. However, according to the disclosure on May 5, there were more documents required for application, and the application site did not work without uploading those.
And then, as late as recent, they clearly explained that only 4 documents are criteria for completeness.
Some people here say that it was our own fault, saying that documents required could be prepared even before the official disclosure one day before May 6.
However, as shown below, checklist for EE (for reference) does not include all of what are required for TR to PR. The list does not include 5669 and it was unknow until later hour of May 5. Meanwhile, 5669 is the biggest reason why some people worry about the worst case scenario.

(note: according to the number at the bottom of the form, it may be an older version possibly in 2010. 2013? version has 5669 on it)
Some may say that 5669 is "common sense", but I do not think so. We are not experts for immigration.
