Not exporting it is fine but are you planning to document 
"zip:storedPermissions"? The version I looked at did document 
"storedPermissions" which amounts to zipfs documenting an interface.

The zip provider can use Files.getOwner and that can be used for group 
when PosixFileAttributeView isn't supported by the file system 
containing the zip file.
