"Gain of function" can be anything a virus wasnt able to do before. If it only spread through physical contact, enabling it to spread via air is a gain of function. If it only spread between Avian species, enabling it to cross into humans (or another species) would be a gain of function. Heck, if it cannot survive in liquid, but you prod it and breed it until it has a variant that survives in liquid that is a gain of function.
Sure, not per se. I meant in this case, hence the "came from a bat or a pengolin" or whatever else. Heck, it could have even come from Fauci's goblin brain.
