But it would still be an additional special case -- and someone might
use malloc(0) specifically as a way to obtain a unique non-null pointer
while allocating minimal memory.  (Of course the could use malloc(1) to
do the same thing.)

What's being suggested is basically a second kind of null pointer, i.e.,
a second unique pointer value that can't be dereferenced.  And if two
malloc(0) calls were allowed to return the same non-null value, that
would require additional wording in the standard.  I don't strongly
object to the idea, but I don't think it's necessary.

And if, say, C26 permitted or required two non-null malloc(0) results to
be equal, code could not rely on that behavior unless it's guaranteed to
be compiled with a C26 or later compiler.  It would be effectively
implementation-defined, but across editions of the standard rather than
implementations.  (There's probably not much existing code that relies
on this.)
