- Trace output in apiserver logs is more organized and comprehensive. Traces are nested, and for all non-long running request endpoints, the entire filter chain is instrumented (e.g. authentication check is included).

La spécification indique aussi que le client peut envoyer un autre champ de formulaire « scope ».

Le nom du champ de formulaire est `scope` (au singulier), mais il s'agit en fait d'une longue chaîne contenant des « scopes » séparés par des espaces.

Chaque « scope » n'est qu'une chaîne (sans espaces).

Ils sont normalement utilisés pour déclarer des permissions de sécurité spécifiques, par exemple :

* `users:read` ou `users:write` sont des exemples courants.
