  OTOH, how many modern architectures have null pointers which are not
all-zeros?

  If you are writing C which must be portable to obscure embedded systems,
microwave ovens, 30-years-old obsolete mainframes and such, then you will
have to take that and a whole lot of other things into account. OTOH, if
you are just writing C for the PC, Mac and a few Unix computers out there,
the rules can often be relaxed a bit.
