Has anyone attempted to use the FOSS version of Determinate Nix?

I'm currently a Lix user, and very interested in the WASM changes and wondering the impact that will have for the nixpkgs repo. When will it start accepting PRs that require wasm support?

It got me thinking, I noticed that Determinate Nix is FOSS. Nothing's stopping someone from submitting a formula to nixpkgs to expose it as a FOSS-community-build of Determinate Nix.

Is there something I'm missing? Anyone down for packaging Determinate Nix?
