The condition does not match the comment, and therefore not the original intention. It currently returns early in *any* type of Nix shell, not just pure ones, including 'nix develop'. Besides being unnecessary, this check prevents Nix shells from functioning properly. For instance, it causes the initialization of the Zsh fpath to be skipped, which is critical. The fact that the user is unable to opt out of this behaviour makes this an ever bigger problem since /etc/zshenv is being loaded unconditionally by Zsh. For reference, NixOS does not perform such check, and apparently never did.
