It shouldn't have to. The PostScript Document Structuring Conventions
allow both forms "%!PS-Adobe-3.0" and "%!PS-Adobe-3.0 EPSF-3.0" with
the rider "Document composition programs should not use these keywords
[namely "EPSF-3.0" and others] when producing a document intended for
printing or display. Instead, they should use only the "%!PS-Adobe-3.0"
comment. Illustration applications may also use the EPSF-3.0 keyword."

Note "may also use". Since an EPS file can be recognised anyway by the
presence of %%BoundingBox somewhere, the EPSF-3.0 is not necessary.

Forcing R to produce "!PS-Adobe-3.0 EPSF-3.0" could break
printing/display software which conforms to the DSC according to the
above quote. The limitations of one program (Framemaker) should not
be used as a reason for producing output which could defeat compliant

However, I wouldn't be against having "EPSF-3.0" as a user-selectable
