I also consider rims a consumable, but due to heart-shape format or too
many eyelets pulled through. I've never worn out a rim's brake surface.

I'm glad you said that. I was feeling inadequate because I don't think
I've ever worn out a rim's brake surface.

I've replaced rims mostly when potholes have damaged them so badly that
I can't jack the dents back out (and I've jacked out several bad dents).
Also when switching from 27" to 700c.

Is there a rule of thumb for how thin I can let a braking surface get?
I'm talking about ancient rims that have no indicator groove.
