first_strip_reply_to = Yes will remove all the incoming Reply-To: addresses but will still add the poster's address to Reply-To: for all three settings of reply_goes_to_list which respectively will result in just the poster's address, the poster's address and the list posting address or the poster's address and the explicit reply_to_address in the outgoing Reply-To: header.
If first_strip_reply_to = No there are two possible situations which aren't covered in your (much improved!) self-doc. Either the original poster included a Reply-To:, or not. If not, then I assume the original From: address is put into the Reply-To: address. Yes? If the original poster included a Reply-To: address then DMARC forces us into a situation in which we can't avoid information loss. Either the poster's Reply-To: is overwritten with the original From:, or the original Reply-To: is retained and the original From: address is lost. Which is it?
