I'm not a stickler for keeping it original, but my instructors keep telling me to stockpile parts while I can, and to save the bad parts in case I'm ever desperate or the new parts don't work the way they're supposed to.
I broke a chain whip on my precious uniglide touring cassette and just about had a heart attack. I wish I would have used an cheap Magna to do my learning on.
The worst thing about the BB is the spindle. If that is pitted it can be hard to track down. I ended up installing a new sealed unit into my Apollo when I couldn't find a replacement. But I have been thinking of buying a small lathe to allow me to resurface this part. Then I will send it off for a cryo bath.
