Worth ASSERTing in a debug build?

You already do runtime checks to make sure AVSampleBufferAudioRenderer and AVSampleBufferDisplayLayer conform to the new protocols, so can you get rid of the HAVE(AVCONTENTKEYSPECIFIER) here and above so you can always create a WebAVStreamDataParserWithKeySpecifierListener to make this easier to read and follow?

Probably not, because we'd have to get rid of the HAVE() checks around the WebAVStreamDataParserWithKeySpecifierListener declaration as well, and that object references AVContentKeySpecifier, which won't be defined when HAVE(AVCONTENTKEYSPECIFIER) is false.
