I expect behavior to change encapsulation!

Node.js 16

@JoostK I don't understand what you mean by defaultChangeDetection.

I mean

const bootstrap = () =>
    platformBrowserDynamic().bootstrapModule(AppBrowserModule, {
        defaultEncapsulation: ViewEncapsulation.ShadowDom,
        defaultChangeDetection: ChangeDetectionStrategy.OnPush
    });

@Component({
  selector: 'app',
  template: 'hello world'  // default OnPush
})

That sounds like a feature request unrelated to this issue report. We don’t have any intentions to widen the JIT configuration options, quite the opposite: these options don’t work in AOT compilations (and never will) and we tend to prefer self-contained components.
