Thanks for the summary. I've been using Meson + Nix, so the comments about using Nix as a build system have been confusing. I think what I've been seeing though are "use Nix instead of Bazel", not "use Nix as your build system".

What I mean is use a relatively simple build system instead of Bazel, and deal with dependencies and reproducibility through a Nix development environment.

You lose out on some of the incremental compilation speed that Bazel offers doing this. I think many in the Bazel space suggest using Bazel inside of a Nix environment.
