Sounds like their target customers are commercial service providers and industrial device manufacturers using NixOS, but need to support stable deployments for longer than NixOS’s current 6 month release cycle. Probably not to applicable for individual desktop users, but they still plan on hosting a public channel and cache for newer releases.
I haven’t gotten around to testing this yet, but I think they just share the Android app proot scaffolding. I wasn’t too satisfied with the proot performance on Android in general using Termux, as with interpreted runtimes like python, the system call overhead really shows itself. That of course doesn’t change here with nix-on-droid.
