Almost all my bikes have dents like that on the chainstays. It used to bug me but since you dont see that part of the bike too often, its outa sight outa mind.

Sometimes I acquire bikes and the kickstands are really good. And there are times where its nice to just prop the bike up with the stand. A good time is when I'm out on a Sunday ride and stop at a popular coffee shop with the local cyclists. Bikes are lined up leaning on the shops windows. I can just drop the kickstand and leave my bike in the middle of the sidewalk. Gives it nice distinguished look, eapecially 'cause its near half a century old.
