I also think it's good to deprecate the old values.   I think we can separate the StringSharingPlugin as a separate plugin option and deprecate --compress 1 as well.   Something like this:


  --compress <compress>               Compression to use in compressing resources:
                                        Accepted values are:  
                                        zip-[0-9], where zip-0 provides no  
                                        compression, and zip-9 provides the 
                                        best compression. Default is zip-6.
                                        Deprecated values:
                                        0:  No compression. Equivalent to zip-0.
                                        1:  Equivalent to --compact-constant-pools
                                        2:  Equivalent to zip-6.
