Is ImmersionRC Ghost protocol not supported?

Looking at the list of compatible radio control systems here, it looks like the ImmersionRC Ghost RC protocol is not (yet) supported, is that right? Is support being planned or in development in copter 4.1?

Also, CRSF is supported so I assume that means TBS Tracer can also be used. Could someone please confirm?

Tracer is supported. You’re the first to ask about Ghost - not currently supported, although you can use it with sbus or srxl I believe. It’s native protocol is not in 4.1, and there’s no timeline on it - but we can have a look.
