I think you might have missed my original point: despite the lack of "fiddly" involved, 0-1-2e didn't have many permanent stat-draining effects at all. Sure, Shadows and Ropers clobbered your Strength but it came back on its own at (I think) a point per hour; and Feeblemind whacked your Intelligence (though Feeblemind's really just a tarted-up version of save-or-die), but not much else did.
Usually, permanent stat drains were just as rare as permanent stat boosts, and often from the same sources.
That is an odd quirk of design indeed.
