Is there a reason why we cannot have a getter for array items?

I like the idea of safe autogenerated getters. But every time I have to check the length of an array I am confused as this job is so routine and dumb that is a perfect match for a autogenerated wrapper.
Consider example

if len(val.GetArrayField()) > 0 {
  val.GetArrayfield()[0].GetSomeNestedField()
}

can become

val.GetArrayfieldItem(0).GetSomeNestedField()

All we need is to generate array getter like this:

func (Value *v) GetArrayfieldItem(int32 index) *Field
if v != nil && index >= 0 && len(val.ArrayField) > index {
  return val.ArrayField[index]
}
return nil

Is there any fundamental reasons why we cannot have array getters like this or nobody just got to do it?

@89z this is just one use case which is already supported. I have use cases when I need a very specific item and accessing it with nested structure becoming ugly. Also, this feature can be configurable.
