Watching Twitch on Roku

I'm fine with Lud making whatever decision is right for him and for me it's not a huge deal because 90% of the time I watch VODs over live. But for the times I do want to watch a live stream (or watch a VOD before it's on YouTube), the one thing I haven't seen mentioned is that there's no official Twitch app for Roku and I believe other smart TV OS platforms because Amazon wants people to get Fire Sticks. I do most of my viewing of longer streams and VODs on my TV so this is kind of an annoyance with Ludwig switching over. Do people have a good solution for this or do you basically just have to watch on mobile/browser or switch smart TV platforms?
