Why will it no longer work? When you forward an email, unless the email forwarder modifies the message content, it should still match the DKIM signature, so it still passes.

I don't know the details but my rough understanding is after forwarding the next hop delivery will fail SPF.

  Yeah, with forwarding, I am seeing DKIM still passes but SPF fails.

    We are seeing all the unix forwarders setup a decade+ ago are dead in the water now (have to be replaced with mailing list software)

  That's my understanding as well, but I also understand that the email will pass DMARC if either SPF or DKIM passes, and DKIM will still pass on forwarded email.
