I think that part of this is because in 1.0 Primals were assumed to have very different lore attached to them, to the point that they seemed to be actual static entities in the lifestream rather than aetherial constructs. This started to change more in 2.0, especially with the remade Moggle Mog, which was our first implication that primals are based off of legends and aren't necessarily real gods. As time went on, it became increasingly clear that Primals are not some sort of aspected deities, but entities created off of beliefs and even feelings.
We've seen primals like Shiva and Thordan, who are mythologized versions of historical figures. It's unknown if the original Shiva had any connection to Ice at all, although her famed husband definitely does. We've seen primals like Alexander, who is based off of a Utopian ideal, or primals like Shinryu who is an abstract representation of rage. Some of them have vague (or not so vague) elemental theming, but it's really secondary or even irrelevant to their status as constructs of prayer and belief. Basically, whatever aspect they share honestly doesn't seem to matter much.
You probably don't even need to use Aether of a particular aspect to summon a specific primal. After all, Ysayle used the (presumably not water aspected) crystals of the Vath to summon Shiva with no problems. You can definitely guess at Elemental Aspects, but frankly they do not appear to matter at all.
