Not that I know of.

Well, any context where wrapping a \score around the file contents would
deliver a working result.

Sure: your files need to have a certain form to make this work (the
problem was putting music and headers in the same file, being able to
strip the headers on demand).  Depending on your preferred form, you
might need to suck into a \book rather than a \score.  Or something
else.

If you need to be more flexible, take a look at
Documentation/snippets/generating-whole-scores-also-book-parts-in-scheme-without-using-the-parser.ly
which redefines several hooks and then is able to include a file of
arbitrary structure (depending on its elements, the various different
hooks get called).
