FWIW, `text-mode` *is* in that category, which is why
`font-lock-fontify-block` does something (i.e. erase `face` properties).

In `text-mode`, `font-lock-mode` is t (if you use default config) yet
font-lock is not actually activated because `font-lock-keywords` is nil.
This is because of the `font-lock-specified-p` test in
`font-lock-default-function`.

I don't much like this distinction between "`font-lock-mode` is non-nil"
and "the font-lock machinery is actually activated".
