We have decided to implement [OpenID Connect 1.0] as a beta feature, it's suggested you only utilize it for testing and
providing feedback, and should take caution in relying on it in production as of now. [OpenID Connect 1.0] and it's
related endpoints are not enabled by default unless you specifically configure the [OpenID Connect 1.0] section.

As [OpenID Connect 1.0] is fairly complex (the [OpenID Connect 1.0] Provider role especially so) it's intentional that
it is both a beta and that the implemented features are part of a thoughtful roadmap. Items that are not immediately
obvious as required (i.e. bug fixes or spec features), will likely be discussed in team meetings or on GitHub issues
before being added to the list. We want to implement this feature in a very thoughtful way in order to avoid security
issues.

## Stages

This section represents the stages involved in implementation of this feature. The stages are either in order of

how important or difficult to implement they are.
