It is referenced in various places, but does not work out of the box:
$ nixos-help
/run/current-system/sw/bin/nixos-help: unable to start a web browser; please set $BROWSER
In the user-hidden fallbacks to xdg-open(1) and w3m(1), nixos-help
expects tools to be deliberately installed by users.
For default installations and new users in general, this is unlikely to
be the case. Conversely, chances to use nixos-help are even higher
in such cases.
Use w3m-nographics by default to ensure documentation is always
available. The documentation browser on ttyS8 already does so, but is
not accessible in every installation, e.g. VMs with only ttyS0 and SSH
available.
This obsoletes including it in the base profile’s systemPackages,
so remove the @TODO as done.

That would require me to sign up at GitHub, which is a Microsoft owned service that uses an EULA I do not agree with.
Furthermore, I do not want to support efforts where projects move their infrastructure to such a centralized monopoly. “GitHub” is becoming more and more of a synonym for “Git” due to the self-evident usage in the FOSS community.
Also, it is 2019 and yet GitHub does not support IPv6.
