It seems like a no-brainer to me. The main role of scouts is unfogging the map. One promotion helps with that, and the other leaves a trivially easy to kill unit slightly less trivially easy to kill.
These are my exact thoughts. My scouts are supposed to scout. Not hang around and escort civilian units. Once the entire map (or at least the major part I want to see) is uncovered then the short period in which the scout, even with survivalism, is useful has passed.
