Yes, this is certainly significant evidence (if any more were needed)
against YEC claims. (Though of course "The light was created in transit" is
still good for laughs.) But besides that, it shows the tremendous advance
in astrophysical techniques over the past few decades. ~1970 trigonometric
parallax was only good out to a few hundred LY. Being able to measure
distances more than 10 times that is something.
