And, amazing as it may seem to some people, we weren't blind to these kind of architectural issues when we wrote RFC 7208. There's even an appendix [1] devoted to discussion of alternatives available to ameliorate such issues. This was argued approximately to death in 2004/2005 when SPF was first standardized and repeatedly since then. I think it's been at least a good decade since anyone had any new ideas on the topic. There is a mailing list devoted to giving people help with SPF [2]. Asking SPF specific questions is really more on topic there.
