Originally, all Tenno were probably dedicated to one frame only due to some limit, and thus useless afterwards. Gara, Mirage, and others that had to be found were unique when they died, but left the blueprints to build them hidden, and I believe most of them died during the final battles of the old war. The tenno and frames were put to sleep because the sentients had won, and were likely tracking the transeference signal, but by cryofreezing them, it lowered the transference, and the operators were kept in a single, safer place, (Lua) to prevent the Corpus, Sentients, and Grineer from ever finding out about the operators, who are seen as generally weaker and more suspectible than the frames. The frames also had to be frozen because they are partly organic, as seen in The Sacrifice Quest, especially the original ones.
