In order to display indexes of 'attachments' in matrix clients, we need the ability to ask the server to provide a filtered event stream of m.room.message events which have a content.msgtype of not m.text or m.emote (or alternatively, explicitly including m.file, m.image, m.video and m.audio). This needs an extension to the v2 filter API to happen.
