I agree, perhaps we could say:

   Note that this feature relies on the default value of
   `mode-line-format' in Emacs 30 and later.  With a custom mode line,
   as well as on Emacs 29 or earlier, add `project-mode-line-format' to
   your `mode-line-format' instead of setting this option.

There's no harm in adding `project-mode-line-format` to
`mode-line-format` in addition to setting `project-mode-line`, but I did
mean "instead" and not "in addition", since the value of
`project-mode-line` is irrelevant if you follow the suggestion to add
`project-mode-line-format` directly to `mode-line-format`.


Best,
