They work for now. But these and future experiments are going to start talking more to the main Test Pilot site, and will possibly break &#x2F; disable themselves without that connection. Going out-of-band to install these will likely lead to sadness eventually.<p>Also, I think you&#x27;re pointing to older demo versions of some of those add-on and not the current Test Pilot releases. We&#x27;re trying to work more in the open on this stuff, so you&#x27;ll likely find things like this here and there.
