The server may optionally enforce a maximum age for unused IDs, and delete media IDs when the client doesn't start the upload in time, or when the upload was interrupted and not resumed in time. The server should include the maximum POSIX millisecond timestamp to complete the upload in the `unused_expires_at` field in the response JSON.

As well as limiting the rate of requests to create `mxc://` URIs, the server should limit the number of concurrent *pending media uploads* a given user can have. A pending media upload is a created `mxc://` URI where (a) the media has not yet been uploaded, and (b) has not yet expired (the `unused_expires_at` timestamp has not yet passed).
