Not that I'm actually involved any more, but I'd endorse the user_regset approach and not the new request. On many (most?) machines, it's already part of the main integer regset (orig_rax et al) and adding another mechanism is redundant. Using user_regset also means there won't be a word of hidden state that is not visible in core dumps.
