There have been MULTIPLE major changes to the requirements for grant citizenship in just the last FOUR YEARS. No one can definitively say what is "correct" about meeting requirements SIX years from now (with at least two federal elections in the meantime).
Beyond that, the plan is rife with RISK. Way, way, way too soon to begin speculating how to navigate the vagaries of what real life will entail for someone who does not even plan to settle in Canada for another three years.
For context and perspective: scores of PRs have planned to make a so-called soft-landing and then return later, within a year or two, to actually settle in Canada, BUT then the twists and turns of real life delayed their actual return to Canada, and many of them have ended up in this forum spilling tales of woe about falling short of meeting the Residency Obligation, and more than a few who did get to Canada in time to be in compliance but still telling tales of woe when, after cutting-it-close, IRCC challenges their accounting of time in Canada. A plan to cut-it-so-close as to just get to Canada barely under-the-wire tends to be foolishly fraught with wishful thinking.
If you are among those super-confident of actually following through on such a cutting-it-close plan, such confidence is a salient sign of . . . well, not the most perspicuous thinking one might say.
