Comment (by swissspidy):

 @TimothyBlynJacobs even `rest_get_route_for_post()` has this same problem,
 as the `wp/v2` namespace is hardcoded there. But at least there's a
 filter.

 To fix this, `WP_REST_Controller` needs a getter to access `$namespace`
 and `$rest_base`. Then functions like `rest_get_route_for_post()` or a
 potential `rest_get_route_for_post_type()` could get the REST controller
 for the entity and get the route via those getters.
