As I mentioned before, this plugin doesn't control the behavior of other plugins in any way. It works straightforwardly, preventing the creation of entitis above the limit. This plugin is using "CanBuild" hook and returns "false" to block entity creation. However, any plugin can create an entity while ignoring this hook. So, it's a matter of whether the developer wants to allow other plugins to prevent creation first. If so, they need to monitor this hook and not create entities if CanBuild returns false. If the developer doesn't want to monitor anything, they simply create the entity. We've already discussed this here right? Nothing has changed since then.
