I refuse to believe that.
Well, believe what you'd like of course, but if you want pure speculation/theorizing:
What would you do if you worked at IRCC and the Minister announced an aggressive target for file processing by the end of the year (aggressive given the covid issues)?
Me, I'd be coming up with some way to search/crawl the files on computer and identify ones that would be candidates for 'fast processing.' Easy files, files with only minor issues, files that likely won't need extensive security screening, files where all docs are scanned and can be evaluated by someone working from home, etc. (Security might be the most significant, ie if they do want to kick a file forward, the first step might be ensuring that 'the agencies' get the security clearance request early)
And then I'd probably find I have to do it multiple times as staff discover roadblocks (lack of biometrics, local offices not open / not functioning, perhaps flags or language found in initial review paras that help narrow the search, etc). At some point these 'candidate files' would get sent to the 'extra decision makers' that the IRCC announcement said would be put on spousal files.
Or it could be as simple as IRCC reallocating files to different offices/officers due to workload, absences, etc, esp as some visa offices are in countries where lockdowns or covid measures make for processing difficulties.
These searches and quick-glance reviews or bumping to a different person/desk/office might all result in ghost updates - which we don't know much about but seem to mean 'something happened to or somebody or some process "touched" a file.'
Now don't get overly optimistic, even if my theory is partially correct, the ghost update(s) may not mean anything more than the system crawled through the database entries, or the opposite of "identify as candidate for fast review." No idea.
But I'd be surprised if IRCC staff weren't doing some kind of triage process to help them meet the Minister's announced targets.
That said, this is pure speculation.
