Also virtual particles don't make sense in a non-perturbative regime like room-temp protons, since they are an aid to understanding terms in the perturbation series expansion.
Not sure how they even apply in the case where Feynman diagrams aren't applicable. Hell, the calculations likely use lattice QCD which eschews them entirely!
