Considering Twitch is moving to a new player, I doubt very much they are concerned about the flash player.
If you don’t need the JS API, you can use the new player. Hopefully Twitch will release an IFrame API when it’s ready (they actually already have one, but it doesn’t work unless origin is Twitch’s main site).
