I don't think it is service time, it is development time. If you take 2-3 years off one way, the chances of recouping value the other way are really slim. If I was drafting I would put no weight in that small probability. I would take the best hitter or pitcher and go with it. If they judge McKay the best pitcher, I can live with that. But if they think Wright is a better pitcher than McKay, but there is also some possible value from McKay hitting if he struggles as a pitcher so they take him, that is a mistake.
