I think using a value other than {0} potentially gives the incorrect
impression that the value is used for *all* elements of the
array/structure, whereas it is only used for the first element. "The
remainder of the aggregate shall be initialized implicitly the same as
objects that have static storage duration."
The rest of the elements are being initialized to zero as interpreted by
their types (so NULL for pointers, 0.0 for floats, even though neither
of them need be bitwise zero). Setting the first item to 0 matches that
exactly.
Using {false} may encourage the unwary to try
bool foo[2] = {true};
which will not set all elements to true.
