It's not useless, but it often doesn't gain you that much. A PDF 1.6 file that uses object streams won't shrink much at all with zip/gzip compression, but PDF 1.3 / 1.4 documents may (depending on their structure). PDFs may compress quite a bit with tools like 7-zip. In any case including true subsets of fonts (rather than converting to outlines or embedding the whole font) would save a lot of space. -- Craig Ringer
