I'm not sure whether OP is upgraded into EuroBusiness on GOT-AMS or even cares.
Agreed on being careful but the agent should be able to tell before rebooking if the GUC will stick or not (and then it is OP decision to say yes or no).
Personally, as long as the GUC sticks TATL, i'd happily take (if needed) the downgrade from "Eurobusiness" (which is a ridiculous name for what the product is).
