Really?  The product literature I have from Dur-O-Wal clearly states that joint reinforcing may be used for both crack control and principal reinforcing.  Also, UBC Section 2106. states that "joint reinforcement may be considered as a part or all of the requirement for minimum reinforcing".

Of course, the loading on the wall may dictate use of more than minimum reinforcing.  I always specify bond beams as horizontal reinforcing for major structural elements in large structures.  But for some applications, joint reinforcing should be adequate.
