	// TODO: do we need `router.route`?
	// https://expressjs.com/en/guide/routing.html#app-route
	// https://expressjs.com/en/4x/api.html#router.route
	// If we do add it, we need to set the case-sensitivity of the sub-router it creates
	// using the case-sensitivity setting of this router.

This is a note to self that if we implement this, and we choose to have route create a subrouter from the router it's called from, to be sure to make the subrouter inherit its settings from its parent.
