Wait, what? Any more details about this, I’ve never heard about that before. Partially run Drop impls sounds like a big potential for undefined behavior, how could catch_unwind possibly cause that?

Yeah, no, I don't think this is true. It's the reason a double panic will cause an abort. The docs do recommend against using this for general error recovery, but there's no mention of any possibillity of inconsistent state.
