Clarification of use of `AVAssetDownloadConfiguration` and `AVAssetDownloadTask` to persist MP3 Audio downloads/streams

Hello! I have been following the UsingAVFoundationToPlayAndPersistHTTPLiveStreams sample code in order to test persisting streams to disk. In addition to support for m3u8, I have noticed in testing that this also seems to work for MP3 Audio, simply by changing the plist entries to point to remote URLs with audio/mpeg content. Is this expected, or are there caveats that I should be aware of?

Thanks you!
