mod_http_oauth2: Strip unknown extra fields from client registration We shouldn't sign things we don't understand! RFC 7591 section-2 states: > The authorization server MUST ignore any client metadata sent by the > client that it does not understand (for instance, by silently removing > unknown metadata from the client's registration record during > processing). Prevents grandfathering in of unvalidated data that might become used later, especially since the 'additionalProperties' schema keyword was removed in 698fef74ce53

Description
===========

This module measures the rate at which text messages are exchanged, and their
encryption status.

::: {.alert .alert-warning}
This module can leak information about your users’ behaviour to anyone who can
access these statistics, so avoid enabling it on a server with few users.
