Has it? IIRC 1.0.0.3 introduced the change and all X570 boards released with that version and all reviewers were told to test with that version (all be it a few days before release and after a lot of them had tested with 1.0.0.2), and AMD have said it's MAX boost so technically they're not saying you will get that speed, just that that's the highest possible (within specs) clock speed
That's not to say i agree with what they've done, i said on another forum a while ago that AMD needed to either sort out the boost behavior or change the misleading advertising, the latter probably being difficult now they had launched, what they've done IMO is the equivalent of giving an "up to" speed.
