I feel like cracks might be a possibility too, but I can't recall if they are directly related to thinning.

I remember practicing a question about failure modes, and I think metal loss was mentioned as a common issue, so maybe that's the right answer?

I think thinning could lead to larger leaks or even rupture, but I'm not entirely sure if that's the most likely outcome.
