I suspect it has something to do with Gmail's policy change on nov 2022 when they started requiring spf, dkim, and dmarc. There are probably a ton of misconfig

  Maybe that's part of it, but to add some datapoints, I've had a bunch of legit email from GMail addresses flagged as spam, and had people tell me that my emails (from a GMail account I've had for ~18 years) landed in spam. (This HN post caused me to check and I found another important GMail-originated message in spam)

    That's just because spammers have wised up and started using Gmail itself to send spam, including old established accounts via weak passwords. Those spam would pass SPF, DKIM, DMARC. It would be both inappropriate and probably illegal for Gmail to automatically mark emails sent by Gmail as non-spam.
