The issue is how well informed the opinion is.
The issue is freaking oneself and others out without justification. There is a lot of misinformation about CIC processes because of how secretive the agency is. Let's not add to the misinformation and anxiety for ourselves and others.
I have found zero indication that "moving too much" within Canada before or after applying for citizenship is an RQ or delay trigger. And I have looked through many thousands of anecdotal reports, CIC documents and ATIP results. Have you looked?
Such proof (or even indication) does not exist. If you have such proof to back up your feelings, please let us know.
The only problem it can cause is if CIC mistakenly or purposefully sends important mail to old addresses. This happens rarely. Much more common is CIC sending important mail to an old address that was never updated and the applicant missing it, and the test/oath/RQ deadline, because their ex-roommate didn't check the mail very often.
The difference between those scenarios is that CIC is at fault in one and the applicant is at fault in the other. When the applicant is at fault for missing an important notice, the CIC is far less understanding.
As applicants we need to minimize the mistakes we make. We cannot control any possible errors that CIC might make.
