This assumes that any such field is atomic, except:
* OwnerReferences: because it has a `+patchStrategy=merge`, but it
probably needs a `+listMapKey=...` ?
* Finalizers: because it hs a `+patchStrategy=merge`, but is a
primitive type (string).
* []byte fields, which should not be failing this anyway (fixed
subsequently).
An alternative approach could be just to turn off the API warnings for
these fields, but it felt more correct to declare the semantics.
