Why is their architecture making it harder on them relevant to the question if it's possible? Because the root question is if it's possible, and there's multiple existence proofs that it's possible. Maybe the VLC developers are just tired. I don't blame them. They had to do a whole refactor to get Chromecast support working, and they got no thanks for that. Or maybe it just wasn't enough thanks and they don't feel like doing another refactor. Chromecast support is quite tricky, I've dug into the protocol.

Anyway, I'm not in control of their development, I'm just pointing out that seeking backwards is possible.
