I think the idea was to make sure that clang-format is in sync what clang regarding extension->language mapping. D90780 <https://reviews.llvm.org/D90780> adds "cuh" as a CUDA extension and this patch, IIUIC, intended to add similar treatment to clang.
So, you are correct that technically this patch is not necessary for clang-format.
Keeping them in sync does have a minor benefit of not raising a question why the two maps are different.
