The "strange reason" is called "AT&T licensing requirements".  SCCS and
"cpio" both require System V source licenses; 4.2BSD does not require such a
license.  The University of California would have plenty of deep legal sh*t
already gotten together for their benefit by AT&T if they offered either
SCCS or "cpio" with 4.2BSD.
