Mhmm.  As James writes, this can easily break.

I can imagine another approach.  Since lilypond itself converts all
fonts to PostScript resources, why not writing those resources to a
`fontresource' directory instead of embedding?  We could add a
checksum to the resource name, just to be sure that, say, `foo.tff'
and `foo.otf' will be rejected.

Ideally, all intermediate PDFs also refer to this `fontresource'
directory, and only in the last step PDFs with subsetted, embedded
fonts are created.
