The project is growing with more features/systems and some of them may be not compatible together like for example builder and avatars moving through comns. Also, some scenes are starting to be perfomance-intensive. If the user want to give all the resources to a scene to speed it up, it should be able to do it. In order to try to tackle this problem, we need a way to disconnect features/systems and scenes
We can implement the isolated modes, when kernel enter in this state, we can pass as a parameter the type of the isolated mode that we want, and kernel will disable all the features/systems or scenes necessary
This way we decouple the knowledge of the systems from the kernel and renderer and we only need to communicate the mode that we want and kernel will do it
In this option, we create in kernel a custom way to disable features/systems and scenes.
This way the renderer can specify which systems/scenes should disable and kernel should act.
This way, we have a granular control in the renderer about what we want to enable/disable
We can also ignore the kernel features in the renderer and control everything from the renderer.
This way we don't need to develop anything additional, however, as the project increase in complexity we should have it into consideration
We went for the option 1: Isolated modes because this way kernel and the renderer will be decoupled and we still can have control about the systems/scenes that are enabled/disabled

In order to implement this ADR we will develop a new message in kernel and the renderer to enable/disable the isolated mode and implement it in the kernel starting with the builder isolated mode that will disable all the scenes and system and add a worker
