Well, to be fair I didn't call it a consensus, only a "most favored suggestion". 
  I agree it didn't have consensus.

That goes only so far.  Suppose the spec for plain traditional strcpy were in 
Annex K, and glibc supplied a strcpy implementation that mostly worked, except 
it failed to copy the trailing null byte.  I doubt whether users would be 
satisfied with the justification "well, this doesn't *conflict* with the spec, 
and it's *partial* support for the standard".  Similarly for a memset_s that 
fails to throw an exception if you invoke it with invalid arguments.
