Angular v9 @NgModule.entryComponents is deprecated

The property entryComponents of the NgModule is an array with components that can be dynamically loaded into the view (as modals). 

In Angular v9 Ivy, it's no longer needed and can be removed in v11. 

In theory it's doing like the java does since the beginning, checking components imported and used into code to generate the deploy bundle.
