I'd be fine with hypothetically sacrificing another Worlds, if it meant winning the Tour in 2024. And to me the best chance Remco has for yellow next year, is riding the Grand Bouclé this time (also for the team, which I don't think is ready yet to shoulder the burden of defending yellow, thus a trial period now would be very usefull).
And even if Evenepoel isn't optimally prepared for Worlds, it doesn't mean he can't still take the rainbow jersey. On the other hand, Belgium also has van Aert's card to play to keep the title for a second year.
I think it is the ITT that would be/is the target and not the RR. Of course, defending the title in the RR would be quite amazing but a lot can happen in that race.
