The sentence (in the blanket rules for the <string.h> function conventions) has no force outside 4.11 in any case, but more specifically it is part of a larger context that you have dropped. The larger context is that some of the 4.11 functions could be requested to operate on nonexistent objects, for example int src[3], dst[10]; memcpy(dst, src, 10); Instead of posting a warning in each function's subsection, the injunction against attempting such abuse is posted in the blanket section.
