I don't think it does mean that IRCC can't extend processing times. Reviewing the actual judgement, it clearly states the minister can set processing times and priorities for application types. The issue in this case was a second Ministers Insteuction was issued that didn't provide transparency or justification for the change. It offers that the Ministers Instruction itself was the justification, which the court determined was not the case. Unless any Ministers Instructions initiated in other immigration streams meet the same criteria, I doubt this will change much regarding processing times, provide those time are accompanied by reasonable and clear justification for the delays. The other consideration is this does not offer a positive result regarding the status of the applicants PR application. It just requires IRCC to decide. The judgement could ultimately result in a positive or negative result, as long as a result is provided in 60 days.
