In my experience of over 15 years, the "rules" have only changed 3 times since I started. First to require good reverse DNS, then to require SPF, last to require DKIM. The transition on each of those was generally several years with plenty of publicity.

That hardly covers it. The problem is that who "you" are, your identity as a sender, is not entirely within your control. The big mail operators figure in a ton of stuff, like the reputation of your subnet - /24 maybe, or /96, it's an approximation - or the reputation of your AS, your domain registrar, all kinds of stuff. If the guy on the next IP over is sending spam that's going to pollute your reputation.
If you have your own ASN and your information is registered with reputable parties in lawful countries, you might not have much to worry about. If you are using a cheap cloud VPS service whose network is registered to a Romanian holding company, nobody will deliver your mail.
You're forgetting DMARC.
If you already have SPF and/or DKIM, adding DMARC is a matter of setting one static DNS record and never changing it again. Hardly difficult.

I don’t have DMARC setup and can still send to Gmail.
