 ### Getting delayed events
 
-#### On demand
-
 New authenticated client-server API endpoints `GET /_matrix/client/v1/delayed_events/scheduled` and
 `GET /_matrix/client/v1/delayed_events/finalised` allows clients to get a list of
 all the delayed events owned by the requesting user that have been scheduled to send, have been sent, or failed to be sent.

 For use cases where the existence of a delayed event is also of interest for other room members
 (e.g. self-destructing messages), it is recommended to include this information in the original/affected event itself.
 
-#### On push

-A new optional key, `finalised_events`, is added to the response body of `/sync`. The shape of its
-value is equivalent to that of the response body of `GET /_matrix/client/v1/delayed_events/finalised`.
-It is an array of the syncing user's delayed events that were sent or failed to be sent after the
-`since` timestamp parameter of the associated `/sync` request, or all of them for full `/sync`s.
-When no such delayed events exist, the `finalised_events` key is absent from the `/sync` response.
-
-A new key, `finalised_events`, is defined for `POST /_matrix/client/v3/user/{userId}/filter`.
-Its value is a boolean which, if set to `false`, causes an associated `/sync` response to exclude
-any `finalised_events` key it may have otherwise included.
-
-The only delayed events included in `finalised_events` are ones that have been retained by the homeserver,
-as per the same retention policies as for the `GET /_matrix/client/v1/delayed_events/finalised` endpoint.
-Additionally, a homeserver may discard finalised delayed events that have been returned by a `/sync` response.
-
-The `finalised_events` key is added to the request bodies of the appservice API `/transactions` endpoint.
-It has the same content as the key for `/sync`, and contains all of the target appservice's delayed events
-that were sent or failed to be sent since the previous transaction.

 A limit on the maximum number of delayed events that can be outstanding at one time could also provide some mitigation against
