Maybe expose them all as global variables prefixed with route or a routeUrl twig function?

{{ routePressReleases }}

{{ routeUrl('name', { userId: 1 }) }}

Craft::$app->urlManager->rules is how we would access any routes defined in the routes.php and in the CP

And then in order to access section routes, we would have to get all the sections Craft::$app->sections->allSections and see which sections have URLs available.
