Being beings of the mothercrystal we could simply be just like those beams then. A manifestation of aether, not a primal like ruda that corrupts aether on a massive scale, still a primal of sorts. We have learned Primal is not a cut and dry thing and they come in many variations.
Sure we do not consume crystals but we also may not be aware that we can if we are unaware we are primals. Perhaps the other primals were unaware of their abilities until they learned what they could do by absorbing crystals. Ysayle showed us a person with the echo can learn to use crystals and take a full primal form and not be detectable when they are not full on primal mode because they are not ever absorbing aether from around them. Having the echo could just be an indicator or a pupal or unrealized primal. And we have fought beside at least 1 primal and it was fine and dandy. So again its ok when we do it. Lore is such a fickle thing.
But the case for us being a Primal is not closed. There are just too many variables and unknowns.
I'm late to the party, but this is actually wrong (though by all means, feel free to correct me if I'm missing something). Behind a spoiler box because it's technically a side-tangent:
(1) Primal lore is not especially convoluted, or at least not the way you're implying - they're beings created from aether and prayer/belief and are both powered by and feed off each.
(2) There aren't really "various types" of Primals. There are really just two: the traditional sort that are formed completely from the above elements, and the sort that are manifested into human bodies. It actually is pretty cut-and-dry.
(3) The reason Primals absorb crystals is because they absorb aether. It's not just something they CAN do, like tempering; it's a fundamental aspect of their nature, because they need aether to exist. This is the entire reason they're so dangerous - they continuously absorb aether from their surroundings, eventually killing the land. Again, this is a fundamental aspect of Primals; nothing in the existing lore shows an exception to this, and there's no reason to believe such a basic piece of the lore will be contradicted any time soon.
(4) Yes, Ysayle and Thordan could manifest themselves into Primals, but you're mis-characterizing the nature of that ability. They weren't permanently Primals capable of hiding and "turning off" their aether-siphoning nature, they were people who were sometimes the host for Primals. When Shiva wasn't manifested, Ysayle stopped being a Primal, which is why she wasn't detectable and didn't consume aether when not Shiva.
(5) Considering all that, as plenty have pointed out, the case for us being a Primal actually is closed. There would have to be a major fundamental shift in the nature of the game's lore to accommodate the Warrior of Light being revealed as a Primal, and it would open a thousand questions as to why Midgardsormr, the various other Primals, the Garleans, and the Scions themselves never even hinted at it. We're just a highly-skilled warrior favored by the Mothercrystal. That's all.
Anyways, I'd welcome a chance to flesh out aspects of my character's backstory more, but it would never be anything more than fluff at best, and would arguably be a bit restrictive at worse. As it stands, we're pretty free to define any and all aspects of our WoL's life prior to rocking up to our city state of choice, and there's no way the dev team could possibly account for the sheer variety of character back stories that surely exist. What I would like is regional/racial quests that flesh out the various settings that characters could come from, as I think this would give more specific contexts for players to form back stories around.
