It is there in 6.00.

'man unzip':

   -L     convert to lowercase any filename originating on  an  uppercase-
          only operating system or file system.  (This was unzip's default
          behavior in releases prior to 5.11; the new default behavior  is
          identical  to  the old behavior with the -U option, which is now
          obsolete and will be removed in a future release.)  Depending on
          the  archiver,  files  archived  under  single-case file systems
          (VMS, old MS-DOS FAT,  etc.)  may  be  stored  as  all-uppercase
          names;  this  can  be  ugly or inconvenient when extracting to a
          case-preserving file system such as OS/2 HPFS or  a  case-sensi-
          tive  one  such  as  under Unix.  By default unzip lists and ex-
          tracts such filenames exactly as they're stored (excepting trun-
          cation, conversion of unsupported characters, etc.); this option
          causes the names of all files from certain systems  to  be  con-
          verted  to lowercase.  The -LL option forces conversion of every
          filename to lowercase, regardless of the originating  file  sys-
          tem.
