See my followup: I think it's probably true that we could skip those
changes. But Rudy commented that there's a lot of underdocumented
subtlety here. There might be reasons I'm missing why we'd need to
stop doing those things. It doesn't seem like DMARC as such would
force that, but perhaps those things trigger some popular antispam
heuristics.
