There’s a user participant project underway creating a categorised directory of radio stations that will eventually be made available in a revamped Internet Radio Browser. I understand there are over a hundred Radio Curators and so no more are needed at this stage.
In my view the project has been a huge success and created a deep and broad directory. There is an element of re-inventing the wheel here, but this way Roon doesn’t have to divert any subscription funds to payment of further licence fees and we get Radio stations that Roon users actually want to listen to.
The directory includes all the working FLAC stations in this thread and any other stations that the Radio Curators listen to or think others might want to listen to. I understand Curators will continue to have an ongoing role adding further user suggested stations and maintaining the directory after release.
As to the timing of any release including the revamped Internet Radio Browser:
Not kidding ! I actually know nothing.
