Not that I disagree with your other arguments but this one sticks out:

My normal usage of localStorage usually looks like this:

    const getItem = (item) => { JSON.parse(window.localStorage.getItem(item)) }
    // and
    const setItem = (item, val) { window.localStorage.setItem(item, JSON.stringify(val)) }

And then you won't have issues with any type.
