Why would a compiler emit extra initialization code for default values
for fields? Not that I object to removing them, but it looks like the
compiler emits unnecessary code in this case.

One can construct torture cases where the semantics are different, for both static and instance fields, if some code change the field value before the initialization is assigned.

For exmple:

class Z {
        static int peek() { return j++; }
        static int i = peek();
        static int j = 0;
