Collection_repository_sync module behaviour

Hello fellow coders,
In Private Automation Hub, when you synchronize a remote collection repository, you are asked if you want to keep local objects (ie collections) which would have been deleted on the remote repository you are synchronizing with.

However, as far as i can see, the module collection_repository_sync has no such parameter; so do you know what happens if you synchronize with this module, and that some remote collections have been deleted , does local objets remain or are deleted too ?

Thanks !
