It is understable from my point of view. IPv6 is a new protocol
and SPF and DKIM are a clue filter to avoid the basic issues we had
in the past.

So it's not really breakage. It's more of a learning curve 8-}

But, if there's a paper from google about the reasoning, I would very much
learn more about it 8-)
