Vuex rompe la encapsulación

Cuando mi proyecto Vue comenzó a expandirse y alcanzó varios cientos de componentes, pensé en el enfoque de Vue y Vuex a la arquitectura del proyecto.

Comencé a usar Vue en mis proyectos hace aproximadamente 3 años. Luego usé js puro para escribir código y creí que js solo está en la interfaz, y NodeJs no es adecuado para proyectos grandes, pero estaba equivocado ...

class UserGetters extends Getters<UserState> {
    get fullName() {
        return this.state.firstName + ' ' + this.state.lastName;

    setFirstName(firstName: string) {
