A service can be converted to a light one

Reports classes that can be marked as light services using the @com.intellij.openapi.components.Service annotation instead of being registered as services in plugin.xml

A service that is not intended for overriding is not required to be registered in the plugin.xml file. Instead, annotate the service class with the @Service annotation. For project-level services, specify @Service(Service.Level.PROJECT).

Requirements:

IntelliJ Platform 2019.3 or newer.
Service class must be final.
serviceInterface is not specified.
If the application-level service is a com.intellij.openapi.components.PersistentStateComponent, roaming must be disabled (roamingType = RoamingType.DISABLED).
None of these attributes is specified: os, client, overrides, id, preload, configurationSchemaKey.

See Services in IntelliJ Platform Plugin SDK docs for more details.
