Which, as a perhaps-unintended side effect, also served as a means of keeping casters' power levels from getting too out of hand at high level...

Well, yes and no. Since most spells had no cap, the saving throw became moot in many cases. If they survived the first fireball, it still did so much damage that the second one took them out. Really, the saving throw didn't matter so much to the monsters because the monsters had so few hit points that a lucky die roll was enough to kill them regardless of whether they saved or not.
Or, put it another way, an 8 hd creature only has 32 hit points on average. A pair of 8 die fireballs is generally enough to mop the floor with most of the creatures.
I know that when I played 1e and 2e, I generally used 75% to 100% hit points for most monsters, just to keep them alive long enough.
