But if malloc(0) returns null, then two such calls don't yield distinct
results.

We already don't know today whether malloc(0) == malloc(0).

Not requiring the non-null return from malloc(0) to be distinct
from previous malloc(0) return values (whether they were freed or not),
could help to "sell" the idea of taking away the null return value.

Some implementors might grumble that null return allowed malloc(0) to be
efficient by not allocating anything. If they were allowed to return
(void *) -1 or something, that would placate that concern.

Say you have a large, sparse vector of dynamic vectors. Sparse in the
sense that most of the dynamic vectors in the sparse vector are empty;
only a few are nonempty. If those empty vectors come from malloc(0) in
an efficient way (nothing is allocated on the heap), that's nice.
