Nice. Bundling everything together was how JupyterLab used to work before version 3, but it required a compilation step to install extensions, which made it inconvenient for users. With JupyterLab 3 (and maybe 4?), if I recall correctly, you could have both worlds - compile some extensions into a base js bundle, then install other extension to be loaded as federated webpack modules.
