you can use page/template init block for this

page root {
init{
if(!loggedIn()){return login();}
}
}

Apparently this doesn’t guarantee the code on the main page isn’t run. If I redirect an unauthenticated user to login in an init block, but try to access some principal field later in the page (e.g. if (principal.role == Admin)), I get a nullpointer. Is that the intended behaviour?

it’s unfortunate but correct according to the current semantics, it could be a nice idea to short circuit when a redirect is triggered in init and skip the rest, but this currently is not implemented that way
