...No. We can't say for certain because we barely know anyone outside of Elpis. You're trying to extrapolate WAY too much about the ancients from our brief visit to their crash dummy testing facility.
Edit: as a research facility they should, but since dynamis had no practical applications in their society it's very likely those who did anything with it kept it as personal projects (like Hermes did) and not as "a product of the facility", so they wouldn't be submitted to the Bureau and they wouldn't get tested in Elpis either.
For starters there's a difference in treatment towards our character. Remember when I mentioned how she keeps calling us "my child", "my champion", "beloved children", etc.? And how she wouldn't address her peers back in ancient days the same way? She doesn't regard us as a fragment of the Azem who succeeded her in the Convocation. She addresses us in a very "maternal" way, like she thinks of us as her creation, rather than the Azem we once were. In fact when she grants her power to the crystal of Azem she speaks of "the crystal's original bearer". Maybe she speaks about the very first Azem, before herself and not about our former self, but keep in mind she never addresses us as the being we once were nor the seat we held, only about "the crystal we possess".
Then as someone else pointed out, she refers to herself as "the last of my kind". So she recognizes "her kind" is different than ours. Call that "kind" whatever you want. Humankind, unsundered, whatever. Point is she makes a distinction that of what they once were she's the only one left. So we're not the same.
That said I don't completely blame you for being confused. She speaks about "mankind" in various instances but then she also makes a differential treatment in others, so it can be confusing to tell if she views the former and sundered humanity as the same thing. She seems to contradict herself a lot through the story, does she not? Not only on this regard. I'd say they just mold her views, her goals and her phrases (and not just hers, really) to "whatever sounds better for the particular scene". She even contradicts herself back to back on the same cutscene. She first says "yeah Y'shtola, it's as you say, I sundered creation so you'd be better equipped to confront dynamis" and then IMMEDIATLY follows with "when confronting Zodiark he was too powerful so my only choice was to sunder creation to diminish his power." So, which is it?
Honestly I can't take anything she says seriously.
