Protect already has a USER flag for that purpose, but mainstream filesystems don't support it. I think it came into being as part of Envoy.

I still don't see much point in multiple users for the sake of security. Sure, it's useful for other purposes such as sharing your computer with other users, but as long as you're the single human user, there's no intrinsic need just to keep up security.
I use my Mac as a single user. In case I need to alter a protected file, the system asks for my password. It could just as well ask for a password without being multi-user.
