I've put a number of the cleanups (though not the trackball page) and mine were to notify that the page has obvious notes like
"THIS IS UNVERIFIED AND MIGHT BREAK YOUR COMPUTER"
or
"more content coming, I'm not finished" etc
If it looks good, take the cleanup out I say. As time wears on others will read your article and continue refinining it if necessary. Leave the cleanup in if there are still any glaring omissions or errors.
