Of course it is.
But lets say all a guy like JRod loses 5 mins today. That will make the mountain stages a lot less interesting.
So it is a part of racing. So is crashes.
Those crosswind stages can be really exciting and dynamic, and I like the echelons. I really lose watching those stages, but I dont necessarily like their impacts on the rest of the race. They might take the edge out of the mountain stages.
I am not saying they shouldnt be in the race at all, I just cross my fingers (see what I did there

) that no of the serious GC guys lose a bunch of time.
Personally I want them all to be fit and close in the GC when they hit AX3
