Welcome back, and thanks for CWA! I only forked it for bug fixes and 2.1 compatibility, so now that you're back there's no need for two mods.
How about I move everything from Next into CWA with PRs: the Nauvis weather, the rain sound fix and the other bug fixes? Then I'd retire Next, and no dependency would be needed.
Since CWA now includes the original Celestial Weather effects too, you could also retitle it "Celestial Weather Next". Only the title would change: the mod name stays, so nothing breaks for players.
