Currently IRCC has gone through a systematic revamp of their applications in making everything digital first. At the same time, the information that applicants are seeking is digital. It's stored in the GCMS, IRCC's database. In many cases, the GCMS notes are pre-flagged for whether they're sensitive or should be excluded from an ATIP request.
There should be a very simple compatibility between IRCC's new portals and an applicant's internal application in officers' notes. An ATIP request should not be filed. Applicants should just be able to see it through their portal.
