DEPRECATED_REASON = """
As of the Train release, the project endpoint API now understands default
roles and system-scoped tokens, making the API more granular by default without
compromising security. The new policy defaults account for these changes
automatically. Be sure to take these new defaults into consideration if you are
relying on overrides in your deployment for the project endpoint API.
