It's not guaranteed to be good as xref:../../05-using-parts-of-my-configuration/index.adoc#using-my-config-with-flakes[Using my config with flakes] but it's an option.
Anyhow, there is a section for using my configuration with channels as shown in xref:../../05-using-parts-of-my-configuration/index.adoc#using-my-config-with-channels[Using my config with channels].
As you can tell, it is made with github:edolstra/flake-compat[opts=repo].
This is to support both use cases easily at the expense of making the traditional method a bit more tedious such as the Nix project being completely locked in with its dependencies (thus you can't configure it with your own nixpkgs version). footnote:[Then again, the way it used to be before flakes already has a host of problems. This is the least of them.]
