And which email clients can do this?
Microsoft Outlook and Mail (Windows 10 and iOS) and Apple Mail in macOS and iOS and iPadOS, at least.
A defacto standard needs to be adopted. If I don't provide SPF or DKIM, I am likely to be deemed spammy, hence a defacto standard has been established. I don't see this with TOTP.
Those almost certainly cover a majority of email client users. And most gmail users simply use the web browser.
