Really, they are the ones who are "so fragile?" Compared to . . .
But the main thing is that reasonable, prudent, sensible applicants can RELAX. No need to get worked up. No need to be anxious. No need to go chasing shadows down rabbit holes. NO NEED to make repeated ATIP requests.
In contrast . . .
That is a good question. That is, does it make a difference where the FP request directs the applicant to submit them?
Most FP requests are in the nature of the most minor form of non-routine processing applicants encounter, having minimal impact on the timeline, requested for verification not investigatory reasons. But of course applicants with significant issues can and often do also get FP requests. Your question might indeed reference a difference related to the reason why the FP request was issued, and thus in some way potentially indicate whether it was for a simple verification of identity or related to an investigatory purpose. But it might just be about the stage the application is in when the request is made.
In any event, most applicants need not worry. Just respond timely, submitting the FPs as instructed, and wait for the next step.
By the way, the applicant probably knows whether there is a concern or issue lurking behind the FP request. Qualified applicants with no reason to anticipate there is any criminal, security, or immigration-status issues in regards to them, can be quite confident the FP request is more or less a formality in verification (resulting in minimal if any delay), and not about some serious investigatory activity (which can cause significant further delay).
That is: For most it is nothing to worry about. For the others, they most likely are aware of what the issue is and why.
If you feel compelled to repeatedly do something that has no productive purpose, will gain you nothing, like making repeated ATIP applications, that is about you. Not about IRCC. Not about how bureaucracy works.
If a neighbour is abusing her dog, that does not excuse let alone justify anyone else abusing theirs.
References to timelines in the time of Covid are not about making excuses. It is a simple fact, IRCC citizenship application processing timelines have slid into extra-slow mode during the pandemic. That is how it currently is. Fantasizing things should be different does not have any more impact on what the timelines actually will be, whether for this or that individual, than pursuing an insane schedule of making ATIP requests.
I understand that much of the posting in the forum these days is about complaining, more than a little spilling into venting, and even some ranting. That's OK. It is readily understood that the timeline is frustrating.
It is not always easy to separate the venting from efforts to genuinely discuss issues or share information. Which is why distinguishing the uselessness of repeated ATIP requests is important in the context in which this comes up so frequently in this forum. Again, the discussion here has tended to invite a lot of confusion and trigger more than a little anxiety. That is not fair to most of those who are naturally anxious to see their applications proceed through the process for whom elevating the confusion and anxiety is hurtful or otherwise makes things more difficult. It is one thing to be impatient. It is an entirely different thing to unnecessarily infect others with unwarranted levels of anxiety.
But overall . . . yeah, most of the August 2020 applicants will be waiting a while longer, and some quite a lot longer. Still, no need to worry. Not for the vast majority anyway. The rest know who they are, and probably why.
