Basically no, I don’t think so. The “legacy” bits flag would block that but thats phased out mostely.
Extensions should offer both bits and not bits enabled stuff. (Like a free tier) But you have to consider that a non affilaited streamer can become affiliated at any point. So they may install your extension ready for that.
You’d just have to include a client side check that uses the isBitsEnabled helper flag. And show alerts accordingly?
