Touch up paint on a top shelf frame is the comfort level for me.
I'm still hemming and hawing over a repaint on a Casati Gold Line S.
I'm starting to come to terms with a repaint of the stays only.
Problem there is a paint match.
I know in my heart it needs it, but I also know how difficult matching paint is in most cases.
By the way, I never blink if others would want to add eyelets or other braze-ons to a frame.
It is their property after all.
