Autoexpiry of DCR-registered clients

11.2. Client IDs:

Implementors SHOULD expire ephemeral Client IDs that are kept in server storage to mitigate the potential for a bad actor to fill server storage with unexpired or otherwise useless Client IDs.

With Solid clients registered via DCR, things can get even worse as the applications normally do not bother (and are not required) to reuse client ID and secret across the sessions, registering a new one upon every user login. Thus, the number of dynamically registered clients could easily reach N_users * N_logins. OTOH, we cannot rely on the user agent for the proper client clean-up (even if we require it). That said, it is even more important for the OP to be able to automatically expire DCR-registered clients rather than the ephemeral ones.

I'd suggest adding this to the Section 11.

Inizia leggendo la Section 11, in particolare le indicazioni esistenti sugli ID client effimeri, e rivedi la motivazione dell’issue relativa ai client registrati tramite DCR. Il lavoro è completato quando si è concordato e aggiunto un testo chiaro nella specifica che copra la scadenza automatica dei client registrati tramite DCR, invece di coprire solo quelli effimeri.
