This should rather be an option, as sometime you want to get out of the nix-shell to edit it and debug it.

Perhaps it should be an option. Personally I think it should be the default behavior and maybe the project as a whole should behave like nix-shell --run "code ."

From the Readme.

One option is to run nix-shell on the command line and then launch code within the activated shell. However, this process can quickly become tedious. Nix Environment Selector provides an alternative: can automatically apply the environment.

The project seems to present its self as a more convenient alternative to opening a terminal and running nix-shell --run "code .", and as a user I felt I need exactly that. That would allow me to enjoy vscode's with out having to constantly launch a terminal.
