But neither the newsletter host nor the email user has any input into how dmarc/dkim/spf are implemented. Only the user's email provider does. And if that's a small business domain, it's likely not very strict with the rules.

I thought DMARC/DKIM was necessary for delivering to Gmail for years now; in any case, there should be few who can't use a backup email to subscribe, as your newsletter won't be the only thing that has these anti-spoof requirements.

Not necessary. Just very highly recommended. I can still deliver my cron emails from a rando host successfully.

That doesn't rule out DKIM, which only requires the `From:` header's domain to list a pubkey and the email to include a DKIM signature from a matching private key.
SPF is the one that regulates which hosts a domain's outbound SMTP servers are on.
