As QwertyMIDX pointed out if a unit gets implemented as a mercenary unit than they would be available for any faction and if that was not the case for the Gaesatae then they will remain as factional/regional troops recruitable only by certain factions (the EDU says Aedui, Arvernii and Carthage only)
