The obvious counterargument would be that in light of that effect, we cannot call Dust strictly elemental. If time distortion effects are possible with Dust, it's unattractive from a storytelling perspective to have it be a possible Semblance. Note as well that I was specifically addressing the possibility of Ozpin having Kiritsugu-like time manipulation as a Semblance. Other sorts of time manipulation run into other issues, principally that they'd be overpowered.
