At some time he would need to find a way to do it.
He can't rely his GT season on Paris - Roubaix. The race with the most chaos, crashes, flats.
He should take this into account.
He will some day.
But he isnt stressed about it. Neither should you be.
And sure PR is a risk, but so is any race really. You can crash when you least expect it. If he wants to win PR, he has to race it. Cant let fear of maybe crashing stop him.
But if he wants to give Vuelta a go... he should race lighter in the spring and no cobbles.
However, this obsession with him doing the Vuelta just needs to stop or the idea that he can or should combine it with all the other races. Something gotta give and he needs a break at some point. Taking it after the Tour just makes the most sense if he races all the monuments in the spring and also be able to go for Worlds and Lombardia.
Not doing the Vuelta is such a small sacrifice, if you can do the other races as good as Pog.
