Correct.
Note that network zones (currently only Meridian and Airplay) can be controlled by remotes today.
The idea is that Roon becomes way much more flexible when these two are separate.
For example, if you want a device to function as an audio zone, you don’t need to run the remote interface all the time, or even meet the graphics requirements – RoonSpeakers is just the audio zone, so it’s very lightweight and can run 24/7 on all kinds of devices.
Conversely, if you have devices you only really use as remotes (like, say a touchscreen computer in the middle of the living room, or a tablet), those can function simply as remotes, without them all showing up in the list of audio zones.
When it makes sense, you’ll of course be able to run the Remote app and the Roonspeakers app on the same device, and then it will be the same experience as when you’re connected to your main Roon install – fully controllable audio zone, and fully functional interface for picking music.
