The thing is that when Remco enters a race it's always for the victory. I don't think he would experience "the stress of the Tour" unless he was going all in for the victory, Hunting for stages is not his bag. Specially if he gets off to a good start and wears the yellow...his hunger for glory and his magnificent strength would push him to go all the way. I could be wrong...I've often been.
It's ironic how it's out that Remco will do, if there is any basis to it, which I highly doubt (as the CN statement seems off), the Giro-Tour double next year. That's because half kidding I previously wrote he should do just that. Not that I would mind, mind you. It would take us back to the era I started with cycling, when it was routine for guys like Hinault, Fignon, Lemond, Roche and others to do so. And they did with great strength in both, at times even winning both. I'd love for that cycling to come back and for Evenepoel, a Belgian, to be the catalyst in making it return. Just think Tadej and others would be induced to take up the challenge. Since at the time cycling (as anyone who was following will surely attest) was so much more engaging than the overly cautious and calculated sport of today, Thankfully, whatever takes place next season, guys like Tadej and Remco are breaking this mold.
I'll only believe it, however, when Remco announces his intention to ride both the Italian and French GTs in January. Although I agree with you that if he does, despite writing he could do his first Tour following the Giro without pressure, he just isn't the rider to race for experience. His talent and determination are such that they wouldn't allow it, which, in any case, would be unseemely to his nature and an ugly sight for his fans. And as you point out the only way to feel the full stress of the Tour, which he needs to grow, is to be in the GC battle.
At the same time I respect Reds take, which doubtless is the wiser approach, namely that Remco doesn't overextend himself at such a tender age. Yet the romantic and nostalgic in me would so love to see his team throw caution to the wind, brake free from this over-programmed and hyper-specialized/robotic sport once and for all, and say fook-all let's just give it a proper go! That would be thrilling, however improbable.
Now one thing to consider is, as has been noted, Remco held top form from San Sebastian to Worlds, but that still isn't doing two GTs back-to-back, the second being the Tour no less. On the other hand, as Patrick has said, in one respect the Tour is easier to go for the win, because the race is the most controlled of GTs, as teams fight to maintain their riders' GC positions. Hence "all" one has to do is follow the train of the leader's team and then beat him to the line. In this sense QS could start with a multi-faceted approach in Remco's first Tour, satisfying both Jacobson's and Ala's stage ambitions, whilst setting him up on the key stages to go with Jumbo and UAE if he is able. It would be tremendous, like opening the windows of a stuffy room shut closed for decades finally to get the stale air out and let in fresh air.
I realize, however, that today's cycling has mastered its own pragramatic formula, for which, given the overall level of the sport this has caused, science and economic interests will likely prevail over heroic, swashbuckling adventure.
