NOT because it's supposed to become a permanent part of the BB, which tends to happen if never removed.
Good point, I'll give you that. I suppose if I was going over a used bike whose maintenance history I didn't know, I would probably get that fixed cup out at some point. But honest, on my own bikes I leave 'em in there, ...greased, not left out in the rain, etc. And without proper tools to get them out and screw them back in you can do more harm than good. Just sayin'.
