I'm not a giging player. I work at playing guitar for myself and have no delusions (for the present) of being good enough to entertain others. So when I put a ding or a scratch on a guitar, it is because I was careless or did something else stupid. I don't get to point at it and say I got that one when a waitress at the bar I was playing at grabbed my butt and startled me. Or when my guitar bumped into Davy Knowles' guitar. No, mine are hollow reminders of something that shouldn't have happened.
But the battle scats on your guitar are different. You can probably remember how you got each one, the venue and what was special or awful (or both) about that gig. Like Hans writes, it's it's a diary. It would be a shame to rip the pages out of it.
If there is something that effects playability, fix that. The rest is your memories and history.
Edit: this is also why I think artificially 'reliced' guitars are a sham. Provenance doesn't come about with tools in the shop - it should be lived.
Oh, and leave those tuners be. Or, if you won't want them and get them replaced, send them to me!
