Prior to the release of Workspace’s PlayerCharacterDestroyBehavior property, it was the case that players and their characters had their parent set to nil, rather than be destroyed. As a consequence, it wasn’t guaranteed that their connections were garbage collected, so it would’ve been good practice to do so yourself
Now that the property exists, if you set it to Enabled, there shouldn’t be a need to manage these connections yourself, unless you experience any issues
