Description
The method signature of PropertyCustomizer.customize declares that it returns Schema but the return value is ignored. If you look at https://github.com/springdoc/springdoc-openapi/blob/master/springdoc-openapi-common/src/main/java/org/springdoc/core/converters/PropertyCustomizingConverter.java#L44 you can see that PropertyCustomizer instances are invoked in a forEach so while they can mutate their property parameter, their return value is never used. That means PropertyCustomizer instances cannot (easily) replace the default schema. Also since the property parameter can sometimes be null there are situations in which they cannot be effective at all.
