A traditional MFE which bundles all of its dependencies and includes the header, footer, and all of the shared dependencies.
A new “guest” MFE with a ModuleFederationPlugin configuration that shares dependencies, and with only the shared dependencies it now needs to be loaded as a runtime module into a “host” MFE. That means the header, footer, core-js, regenerator-runtime, and brand are no longer included at all.
