Imo unless you've already won the Tour or are a clear contender, going to TdS or Dauphine expressly to "test your legs" or "preparation" is pretty disrespectful, although I know many view it that way. Certainly Remco would like to win it, as will most of the peloton I suppose.
Not being a major goal doesn't mean they don't want to win it. But the same is true for all those other contenders like you say. Of course you want to win in every race you participate, but having that drive doesn't mean that it was a major goal.
The same thing you see in the early classics, yes every favourite for rvv/pr will try to win that as well if they start, but its not like they peaked early to specifically win that race.
And this is the part of Remco, he will try to win it or fail trying. but that doesn't mean he 'peaked' for this race. Want to make it clear cut, because there is a difference in expectations and results depending on your intention/preparation state.
If we go for this is a major goal, him not winning or at least making a huge impression would be a huge let down and some will spell doom and gloom.
Making clear this is a preparation race sets the minds more that he is also not in his peak form/abilities and we shouldn't judge it as that as well.
I know, might be nitpicking, but tbh in this forum it is better to be clear as expectations can go really wild very fast
