With that, the operation IDs would be renamed from things like `items-get_items` to just `get_items`, that way the client generator can generate simpler method names.

It's acceptable for implementation classes to be written to fit into existing code, but new classes must not instantiate managed properties or implement getters manually.

This is preferred:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()
}
```

This is acceptable:

```groovy
public interface NewThing {

        // Current behavior of test impl: returns same reference
        assertSame(raw, t.toByteArray(), "should return the same reference as mechanismToken");
    }

    @Test
    @DisplayName("Setters accept null and getters return null")
    void settersAcceptNull() {
        TestSpnegoToken t = new TestSpnegoToken();
        t.setMechanismToken(null);
        t.setMechanismListMIC(null);
