Found it (man XPG4):

  Utilities
     If the behavior required by POSIX.2, POSIX.2a, XPG4, SUS, or
     SUSv2  conflicts  with  historical Solaris utility behavior,
     the original Solaris version of the utility is unchanged;  a
     new version that is standard-conforming has been provided in
     /usr/xpg4/bin. For applications wishing to take advantage of
     POSIX.2,  POSIX.2a,  XPG4,  SUS, or SUSv2 features, the PATH
     (sh or ksh) or path (csh) environment  variables  should  be
     set  with  /usr/xpg4/bin  preceding any other directories in
     which  utilities   specified  by  those  specifications  are
     found, such as /bin, /usr/bin, /usr/ucb, and /usr/ccs/bin.


But Solaris is far from only system that has the old-syntax sh as /bin/sh.
