CppInterOp is capable of building against the head of the release branches, and this is what we do in our ci. Without this patch we are unable to run our Emscripten tests in our PR to upgrade to llvm 20 here https://github.com/compiler-research/CppInterOp/pull/491 . This patch is part of the PR currently to show that it helps, but I'd rather not have to carry along such a large patch as part of our build, and have this goes get merged into the release branch instead, as the chances of a conflict when trying to apply the patch is highly probable in my opinion. A conflict is a reason why this patch had to be back ported instead of cherry picked.
