Uhm, not really. An SPF failure is really bad even though DKIM works. It might depend what they do with DMARC but even so, there's no reason they can't just add that IP to their SPF record.
SPF has from day one been known to be broken with mailing lists. It's not "really bad", it's just what it is. There are other modes that SPF fails too like forwarding. Frankly I've tried to keep clear of "SPF is pointless", but it is actually pointless. It doesn't bring anything to the table that DKIM can't do better.
