Yeah, quite possible. You can construct the feed by some rules, mine are here: https://github.com/pipes-digital/pipes/blob/4243c9234ddab6a3... - but then you have to monitor whether it still works periodically. Being able to replace that by proper meta tags would be nice.
Using openrss.org as an intermediary might work as well, but not ideal to rely on a third party for that.
But on a first glance, it seems like alternate links for channels are back, but playlists are missing. Still, that might be a step forward.
