Passing Pathname to resolve not allowed

[backstromjoel]

Describe the bug

When calling resolve(route) with a route thats a Pathname, you get a TS2345.

The behavior I was expecting was for resolve to accept a Pathname or a RouteId, not just the string literal.

If this behnavior is indented, could we clarify why and how to handle dynamically created routes (variables) using resolve? https://svelte.dev/docs/kit/$app-paths#resolve

Reproduction

<script lang="ts">
	import type { Pathname } from '$app/types';
	import { resolve } from '$app/paths';

	const route = '/' as Pathname;
</script>

<a href={resolve(route)}> Example </a>
