• [nitpick] Consider renaming the field and JSON tag to 'FieldOverriders' (plural) for consistency with the other overrider fields (e.g., AnnotationsOverrider) to improve clarity.

FieldOverrider []FieldOverrider `json:"fieldOverrider,omitempty"`

• [nitpick] Consider renaming the JSON field to "fieldOverriders" for consistency with other overrider fields (e.g. AnnotationsOverrider) which use plural naming.

FieldOverrider []FieldOverrider `json:"fieldOverrider,omitempty"`

operator/constants/constants.go:1

• The removal of the operator/constants/constants.go file should be verified to ensure it is intentional, as it may affect parts of the system that rely on these constants.
