I'm not speaking for Stephen... But Microsoft supports sensitivity
levels in Office 365. See
https://support.microsoft.com/en-us/office/apply-sensitivity-labels-to-your-files-2f96e7cd-d5a4-403b-8bd7-4cc636bae0f9.

For general email, I believe you can use the Sensitivity: email header
from RFC 1327. Or maybe use an X-header.

The BNF for RFC 1327 Sensitivity: is kind of lame:

sensitivity     = "Personal" / "Private" /
                     "Company-Confidential"

So I would expect to see modern mail user agents use the X-headers to
express finer grain classification.
