Which lead to Matrix Supergirl, Kandor-That-Isn't-Kandor, Eradicator, Pocket Universe Zod and **** like that... you cannot have your cake and eat it too. I can see the appeal of the idea but you just have to sacrifice so much to make it work. Kryptonians appeared already in the early 50s, so.
When an idea is out of the bag you simply cannot kill it. Writers and editors (especially) will never have the discipline to keep him the sole survivors, sooner or later the first cop-outs happen and then they don't care anymore.
