 4. Boolean route params are transformed correctly for the URL. In the above
    example the resulting query parameter will be the existence of `?checked`
    not `?checked=true` and `?checked=false`
-5. Route params can be used as a state for input elements. In order to retrieve and update the route properties
-   we can use events. For example `<KCheckBox :model-value="route.params.checked" @change="(value) => route.update({ checked: value })" />`
-   will automatically sync the checkbox state to the `?checked` query parameter. This aims to make it easier to maintain
-   state in the browser URL and harder not to. Note that this does not work when using the two-way binding attribute `v-model`.
