The two commits made sense. And resolved most if not all of my major concerns.

I see, and I understand that this review process became much longer than the ideal. Unfortunately, I have major concerns with this PR and would not like to merge it as is. Based on your comments I suspect that you are misunderstanding the situation, and that's what I'm trying to explain in my long comment https://github.com/llvm/llvm-project/pull/139256#issuecomment-2895183010 .

Just please let me return to the trivial solution where each `CheckerFamily` directly defines its `StringRef getDebugName() override { return ClassName; }`. I'm strongly convinced that this is the most elegant approach (as I explained this in my long comment https://github.com/llvm/llvm-project/pull/139256#issuecomment-2895183010 ).

I would not be opposed to eliminate this one last piece of boilerplate in follow-up commits _if there is a clear solution_ but the current state of this PR is NOT a clear solution.
