I would certainly rather see this than {isAdmin: bool; isLoggedIn: bool}. With boolean | null, at least illegal states are unrepresentable... even if the legal states are represented in an... interesting way.

Admin false LoggedIn false doesn't feel illegal to me, more redundant if anything

I was thinking of the three legal states as:

not logged in (null or {isAdmin: false, isLoggedIn: false})
logged in as non-admin (false or {isAdmin: false, isLoggedIn: true})
logged in as admin (true or {isAdmin: true, isLoggedIn: true})

which leaves {isAdmin: true, isLoggedIn: false} as an invalid, nonsensical state. (How would you know the user's an admin if they're not logged in?) Of course, in a different context, all four states could potentially be distinctly meaningful.
