It is an POC repository that is still improving.

This is a security and safety feature: if an account has a restricted shell (not listed in /etc/shells), they can't upgrade their access by switching to another shell; and a user can't lock themselves out by switching to a shell that they can't change from. The root user is of course exempt from this restriction.

As to having nix in home-manager itself, it is not necessary and up to the end user. Having it in there automatically upgrades nix on new deployments, and builds it in one go when building home-manager, but it also makes initial deployment trickier, as the first time nix itself has to be uninstalled from the user environment.
