Today these forwarding doesn't work at all.

struct S { void opDispatch(string op, A...)(A args){} }
void main() {
    S s;
    +s;     // not converted to opDispatch!("opUnary", ...)
    s + s;  // not converted to opDispatch!("opBinary", ...)
    s();    // not converted to opDispatch!("opCall", ...)
}

So I think this is an enhancement rather than a bug.

I think no. At least, constructor and destructor have some special features
(e.g. can modify const members for construction), but opDispatch doesn't.
