We don't need a library that requires as much boilerplate code as
writing the AuthGuard ourselves, especially since the token validation
was already custom code by us.
The previous name PublicAuthToken was a bit misleading, since PublicAuth
could also be interpreted as being used for the public frontend in
contrast to the API. The old name before that (AuthToken) wasn't better
since it wasn't clear what type of auth is meant. I know, this is the
second renaming of the same module in less than a month. However, I
would say the name ApiToken seems rather reasonable and understandable.
