Right, obfuscation. That's about the only use case I could come up with.
Well, if someone is bothered by the lack of support, libarchive has a
bug tracker on code.google.com :) I wouldn't find out in 10min whether
zip sets the bits in the pre-file header or only in the central
directory. The former would be a requirement of being able to implement
this in any sane way though.
