Even

> "an anonymous user must never edit any data, except for the create account form"

Can quickly end up being

> "an anonymous user must never edit any data, except for the create account form, and the feedback form"

And a week later go to

> "an anonymous user must never edit any data, except for the create account form, the feedback form, and the error submission form if they end up with a specific type of error"

And then during christmas

> > "an anonymous user must never edit any data, except for the create account form, the feedback form, and the error submission form if they end up with a specific type of error, and the order submission form if they visit it from this magic link. Those visiting from the magic link, should not be able to use the feedback form (marge had a bad experience last christmas going through feedbacks from the promotional campaign)"

It is still a small rule, with plenty of value. It's nowhere near the size of the access control for the entire site. And it's also not written down by construction.

It changing with time doesn't make any of that change.
