DKIM, DMARC, SPF, rDNS/PTR, EHLO… all correct and verified in the email “original source,” BY GOOGLE. Still goes to SPAM folder because **** you, apparently. I hate Google.

Frankly, I’m rather shocked it hasn’t happened by now.
We’ve tried to bandaid over it with various weird things, but fundamentally SMTP is just weird.
I could easily imagine a domain having some SRV record to advertise “hey, I support NeoSMTP”, and peers switching to that instead, possibly pinning on successful NeoSMTP negotiation.
Get rid of a lot of the relaying which has not been useful in modern times and only a liability, and perhaps offer an https option to be less likely to be blocked (a TXT record to indicate url, and a node could declare their NeoSMTP entry point as https://mail.server/NeoSMTP/ or whatever works for them).
Jmap is also an emerging standard. https://jmap.io/
