It's not used in this PR, and I find it difficult to add test for.
However, in my next PR it's gonna be [used](https://github.com/llvm/llvm-project/pull/95129/files#diff-7c4020235aab08e99f0a84abd569c43e01e5b0ce6ac2182ef1deda8b487734b5R88).

The dump methods are for just debugging, like for the other APIs. This way they remain consistent.
