@ck yeah, I completely agree. We are in the difficult position of needing plenty of groundwork to be done before typical Nix users could move over to a different package set (a migration which would be tough on its own).
The package set is coming along, but is still quite small. No work has been done on a NixOS alternative yet, so that will take even longer (and come after the package set is capable of supplying OS packages).
I had hoped that some people capable of contributing to that foundational tech would have moved over from Nix, but that didn't seem to happen. Still, I hope to get things usable one day...
