Even if there were no weather issues, there is always the looming risk that stages will be cancelled due to spectator problems; which is more of a concern now, than ever, with the safety mandates in place. So, if the organisers had split the stages, there would be 2 medium length stages to be ruined / cancelled rather than just 1 long one. Which ever way you look at it, less stages means increased risk of loosing huge mileage.
