Apparently I've read the patch notes more carefully than most because they make no mention of this. The new job guide does not make reference to this either.

Regardless, I choose to believe you. As you are apparently experts on all things FFXIV. I still find it odd that they choose to combine Stone into 1 + 2 + 3 + 4 as you level up but do not do this for aero leaving aero 2 and aero 3 separate.
