I’ve not experienced this problem sending emails via IPv6 to gmail

Likely this email will, in fact, get sent to GMAIL via IPv6.
I do have good SPF and DKIM records and signing and a reasonable DMARC
policy set up.
If ISC doesn’t have that yet, it might be a better alternative than
turning off IPv6.
If that doesn’t solve it, I can reach out to someone at Google who can
likely get the right parties involved.

I think it has been argued before that having a different email
acceptance policy over IPv4 vs IPv6 is essentially a layering violation.
I'm sympathetic to that argument.
More to the point: *you* could do this and there are a number of other
clueful people who can make this work today. And when Google changes
their rules (that you'll have to learn about once you hit the next
wall), then you adjust. And you keep on doing this whack-a-mole game.
Of course there's an argument that say "mom and pop should not run their
own mailserver, there are professionals for that!" but at the end of the
day what this really serves is deliberate and pre-mediated
centralisation, slowly but steadily stamping out small players.
