The second use case that I'm trying to address is when a sender only wants to receive feedback reports on message disposition and not alter email processing in any way. I don't want a DMARC p=none to alter anything the SPF is doing (-all or ~all). I also don't want DMARC to alter processing of and ADSP record if present.
