The new approach works as follows. The initialization is performed up-to a certain depth. However, this makes it hard for the mutator to select fields in deeper layers. To get around this, during mutation, we assign a weight to non-present proto fields based on their estimated number of sub-fields. PiperOrigin-RevId: 712897465
