Actually, that's a new innovation.  A good one, though.

Possible, but not desirable.  If you're going to have to use this if/else
 statement every time you use realloc(), you might as well put it into
  realloc().  And that's why ANSI-conforming realloc()s do just that.

I saw no such assumption, no "damn lazy programming" and no "sorry excuses
 for not being defensive."  Steve Summit's article was, in fact, quite
  helpful.
