Unfortunately, in the following (unexpected) setup

  == a.org ==
  #+SETUPFILE: b.org

  == b.org ==
  #+TITLE: Something

modifying "b.org" changes title for "a.org", even though the latter is
not modified. A dag would be needed to handle this case.

The same goes for #+INCLUDE keywords.

Overkill, IMO.

Fine by me. I suggest to mention previous caveat in the docstring.
