I may be wrong, but it seems that in this case T.init will yield a 
temporary, while static T empty is 'always' there.

Consider:

struct S {}

void main()
{
	writefln("%x", &S.init); // prints one value
	writefln("%x", &S.init); // prints another value

	static S s;

	writefln("%x", &s); // prints one value
	writefln("%x", &s); // prints the same value
}
