Would have been nice to see a comparison to alternates who were otherwise qualified but did not fly shuttles.

Seems weird, but if they had actually done that (much better) experiment (which has a moderate to high chance of detecting no meaningful difference) it's quite likely the result would not be "interesting" enough to be published in a major journal.

With identical twins, one of each pair gets to fly, the other stays on the ground. They could also look for time dilation effects ;)
