Indeed. Just speaking from a signals point of view, frequency hopping is not competitive for high bandwidth applications. It is however surprisingly durable in the presence of interference despite its simplicity. We’re seeing this play out in newer Bluetooth standards.

Isn't it still extensively used for RC stuff like drones and model aeroplanes / cars though? Asking as an amateur.

It very much is! It's widely touted as a safety feature, since interference on one frequency means you wont lose control of the flying blender for more than a few milliseconds (well, usually...)

Yes. It works well because this is an application that requires low bandwidth, and interference could cause you to lose control and is even expected with multiple operators in the vicinity. You definitely want to have resilience to other interfering signals.
