The generic ATIP application does NOT result in anyone making a physical copy. The applicant receives a copy of a report generated from GCMS, a report which is specifically designed for sharing with the applicant. And, unfortunately, a report which reveals very little if anything which an applicant does not otherwise know or can easily deduce.
There are some situations in which it is a good idea to apply for a copy of your records. However, these tend to be uncommon. In such situations a customized application is more likely to result in a response containing useful information. Making the customized application is more complicated and demands doing some serious homework, in order to craftily compose the request in a way which will actually result in getting real information.
There is no direct penalty for obtaining a copy of one's records. Of course, however, every access to the applicant's records itself becomes a part of the record (even the version of the GCMS record generated for applicants will show dates and events when the file was accessed). So the decision-maker will, naturally, know the applicant has applied for a copy of his or her records. How that might affect the exercise of the decision-maker's discretion is difficult to forecast. In isolation, it probably does NOT invite suspicion. If there are other aspects of the application suggesting cause for concern, who knows.
Please do not mimic the aberrant and abhorrent behavior of those who abuse the system making multiple unnecessary applications for a copy of their records. That behavior, beyond being what it is and deserving all sorts of derogatory attributions, cumulatively has a huge impact on the allocation of IRCC resources and is undoubtedly causing the processing of everyone else's application to be slower. Which most here would not appreciate. For obvious and good reason.
