The MediaItemFiller is not flexible enough for most realworld usages because: - it doesn't allow asynchronous resolution of MediaItems (e.g. to look up URIs from a database) - it doesn't allow to batch updates for multiple items or do more advanced customizations (e.g. expanding a mediaId representing a playlist to multiple items). Both issues can be solved by passing in a list of items and returning a ListenableFuture. The callback itself can also move into MediaSession.Callback for consistency with the other callbacks.
