Yes, this is for RELENG_4 compatibility.

   I've found file creation time (UFS2-only recent addition, see e.g. ls -U) 
_very_ useful. It always made me wonder why UNIX doesn't support such a
basic and useful functionality (all DEC's ODS-* filesystems support it IIRC).
Now I can e.g. issue 'ls -lU /var/db/pkg' and this will show when each package
was _installed_ (and not _modified_ as plain 'ls -l' shows). For UFS1 ls -lU
always gives "Jan  1  1970" ;)

Sincerely, Dmitry
