Not exactly due to portability problems, but due to the fact that
there are so many broken ports of 'find' and 'xargs', at least for
Windows, out there.  Using "grep -R" would indeed be better.  (Btw, on
GNU/Linux "grep -R" is _slower_ that "find | xargs grep" pipe.  But on
Windows, "grep -R" is faster, even with my "improved" and fast port of
GNU Find.)
