This is probably because SUSv2 is almost as old as POSIX.1-1996 (which
has the prerequisite).
BTW, <unistd.h> has the same prerequisite, but our version of <unistd.h>
is polluted with an include of <sys.types.h>. Nevertheless, we fixed
several man pages to document the old-POSIX requirements. E.g.:
RCS file: /home/ncvs/src/lib/libc/sys/fork.2,v
Working file: fork.2
head: 1.14
...

Add <sys/types.h> to synopsis.
Correct a grammatical error.
Add cross-reference to setrlimit(2).
Obtained from: OpenBSD

ISTR that most of the fixes came from OpenBSD. I haven't attempted to
fix unistd.h since its pollution is old. I only police new pollution
and must have been asleep when we broke several man pages to undocument
the old-POSIX requirements. E.g.:
RCS file: /home/ncvs/src/lib/libc/sys/setsid.2,v
Working file: setsid.2
head: 1.12
...
----------------------------
revision 1.6
date: 1997/04/08 10:43:47; author: peter; state: Exp; lines: +1 -1
setsid is declared in <unistd.h>, which is self sufficient (doesn't need
prior <sys/types.h>)
