PaymentMethodsResponse.toString() modifies response?

Java version: 1.8 Library version: 4.0.1 Description Why does the toString() function in PaymentMethodsResponse.java modify the response from Adyen by appending stuff like "class PaymentMethodsResponse." Surely the main usecase for this function would be people using dropin or a component interested in passing this result into the component. Seems silly I have to write my own toString() function in order to do this as opposed to the default toString function stringifying the /paymentMethods result.
For example, this is the response of toString() currently:
class PaymentMethodsResponse {
    oneClickPaymentMethods: null
    paymentMethods: [class PaymentMethod {
        brands: null
        configuration: null
        details: [class InputDetail {
            configuration: null
            details: null
            itemSearchUrl: null
            items: [class Item {
                id: 1121
                name: Test Issuer
            }, class Item {
                id: 1154
                name: Test Issuer 5
            }...]
        group: null
        name: iDEAL
        paymentMethodData: null
        supportsRecurring: true
        type: ideal
    }, class PaymentMethod {
