What's important to note is that while the work is suggestive, it's far from conclusive. The author notes, however, that "even stronger results than the present results are expected with later data releases of Gaia." So, presumably, we'll have more evidence very soon --- and, if not, the way to bet is that this finding will turn out to be due to the instrumentation's margins of uncertainty. The author also notes that "a recent study by Mistele (2023) showed that predictions of the AeST theory agree broadly with the results of this work." Which suggests that the AeST theory might be worth a look!
