I didn't add that because this patch is logically part of D128745 <https://reviews.llvm.org/D128745> which has a release note already.

I think GCC is the one that is not conforming. MSVC agrees it is ambiguous (https://godbolt.org/z/T5zbxaTYq). Basically, only the first parameter is considered for partial ordering. (https://eel.is/c++draft/temp.deduct.partial#3.1)
