What is the meaning of lazy-initialization in Spring Boot properties file ?

In one of our projects in company. A teammate did this long time ago, and I don't get why ? The property documentation says :
Whether initialization should be performed lazily. - default value is false 
spring:
  main:
    lazy-initialization: true
spring:
  main:
    lazy-initialization: true

IIRC that should be about bean initialization so if you have 
@Component
public class SomeComponent {
  @Autowired
  private OtherComponent other;
}
@Component
public class SomeComponent {
  @Autowired
  private OtherComponent other;
}
then lazy initialization allows Spring to create and register SomeComponent before the OtherComponent bean is fully initialized nvm not that it means that if you declare a bean, it will only be created when it's actually needed

so that property makes all beans in the app lazy ?

it can delay errors so if there's something wrong with a bean, the application might still start but cause exceptions in the future with eager initialization, you see these exceptions directly when the applicatio starts up so you immediately know when something is wrong
