There are also unresolved codec issues with playing videos (no H264 support), so even if we do enable video playback it'll not be available everywhere, and even in places where it is it is going to be a biggish battery sink (no hardware decoding support). Would want to consider that before enabling it fully.
Also, I'm sortof sure that the actual people who did the media work do not actually subscribe to mobile-l. In general, I think we should use wikitech-l for all tech discussions.
