Luci clarification on ubus

For Developers
1

@jow I notice that in luci.js we have this

if (rpcBaseURL == null) {
				var rpcFallbackURL = this.url('admin/ubus');

				rpcBaseURL = Request.get('/ubus/').then(function(res) {
					return (rpcBaseURL = (res.status == 400) ? '/ubus/' : rpcFallbackURL);
				}, function() {
					return (rpcBaseURL = rpcFallbackURL);
				}).then(function(url) {
					try {
						window.sessionStorage.setItem('rpcBaseURL', url);
					}
					catch (e) { }

					return url;
				});
			}

is /ubus/ still not implemented or i'm missing something?

(this is to fix a 404 error from nginx)

It tests if uhttpd-mod-ubus is available and if not, it falls back to a cgi based emulation
