    Top level APIs will likely receive an overhaul to avoid globally mutating the
    Vue runtime when installing plugins. Instead, plugins will be applied and scoped
    to a component tree. This will make it easier to test components that rely on
    specific plugins, and also make it possible to mount multiple Vue applications
    on the same page with different plugins, but using the same Vue runtime
