I haven't received a reply for my concerns I commented at https://github.com/llvm/llvm-project/pull/117121#issuecomment-2502346476 and https://github.com/llvm/llvm-project/pull/117121#issuecomment-2516251353, and they still remain for the alternative proposal.

I'd recommend working on better defining the problem, and then working on a well-defined solution for the problem that doesn't affect or conflict with a currently well-defined solution to a different problem (i.e., KCFI).
