Comment (by mreishus):

 I'm happy to revive this; `get_routes()` in the meantime now has a
 parameter: `get_routes( $route_namespace )`. I came up with an idea in the
 attached patch above, but it doesn't feel quite right. Any ideas?

 This patch also doesn't solve the problem of `get_routes()` being called
 more than once, because the `$route_namespace` optimization was applied to
 the main callsite of `get_routes()`, but not the others. But that could be
 tackled as a second step.
