Okay, second try at a comment.

I was disappointed by this video. I'm unaffiliated with any keyboard company and
generally appreciate distance from the displeasure of capitalism. I just like
keyboards. Building a genuine community brand requires more than just a quality
product. The human element is also your brand. And this includes respect for
those whose work you have built on top of (Kaleidoscope and Crysalis). I suspect
the Keyboard.io folk are too empathetic to participate in this competitive and
unfair teardown, which motivates me to author this response.

I understand how names are set explicitly on NIX_PATH:

$ NIX_PATH=nixpkgs=/nix/var/nix/profiles/per-user/root/channels/nixos \
>     nix eval nixpkgs.lib.version 
"19.03pre155751.45a419ab5a2"

But this seems to indicate that raw paths can be put on NIX_PATH to override settings:

$ NIX_PATH=/home/tnks/.nix-defexpr/channels:nixpkgs=/nix/var/nix/profiles/per-user/root/channels/nixos \
>     nix eval nixpkgs.lib.version
