Suppose I have an elisp file and I change to org-mode by hitting "M-x org-mode".
The code does not get highlighted because it is not embedded within org-babel
construct.
If I have a programming language file with some org-mode heading commands in it,
and change to org-mode, it would be neat to have language highlighting
available.

It is certainly useful but not always. Outline could have a switch, that
toggles between highlight and no-highlight.
