My idea on the original warframe concept is after they recovered the 10-0, the war with the sentients was already on a loosing side and they went back to basic-combat, as guns and blades. Harnassing insane power of the void, they initialy experiemented to putting the kids into suits to control their powers. As casualties still occurred, they used technology to blueprint any of these kids and their frames, to create surrogates (sentients could already adept to anything, cloning human-void-hybrids wouldn't be that hard). It was then Margulis who found a way to let the kids use the surrogates remotely, skilled as they were trained but fearless for dying. From there you know the story to Natah.

As the original frames eventualy died, their blueprints still have bits of their original self inside, like dna, hench the 'personality' on several frames (like valkyr). My idea is when the 'frame' noticed the end, that little bit of original self got activated and gave it the final push, breaking the sword.

Alongside I believe Shadow is the only 'original' frame still left, though during the cutscene you see him and the operator move their hands sort of in sync. That makes me believe the Transference was already done in a earlier stage, surrogates weren't just clones, but heavily mutated people.
