It wasnt lifted until the 2000s
Though STAS actually did feature a pair of kryptonians acting as zod and faora stand ins, they were just thrown into a black hole at the end of their second appearance to ensure superman stayed the last son of krypton
supergirl in STAS was heavily re-written around the limitations to be kara in-ze rather than kara zor-el, and from technically not krypton in order to fit the mandate
But it ended up being a distinction without difference because they treated her as if she was kara zor-el anyways
Still not as weird as post-crisis supergirl being a clone of lana lang made by good lex luthor from another dimension
