C1a2 is extremely rare in whgs, i think only the labrana has it
but yes their mtdna, while being much more common among anatolian farmers was present very sporadically in mesolithic europeans

however i offer you another possible piece of evidence, the biomuse project released some previews of their study a few years ago, and a mesolithic HG from the middle of the agean seems to be ahg genetically
for now everything is debatable but i believe that they were ahgs
