So instead of installing multiple nuclide packages on change we need to deactivate / activate from the nuclide core. Though integrating nuclide by default could be veeeery slow during installation. Maybe lazy load it until the user actually sets a nuclide option?

If this new nuclide is faster than the previous one, we could also think about making the nuclide tree and quick open the default option

Configs for disabling all packages:
