I actually do think you’re being unreasonable.
This is 3rd party development, and we’re at the whim of Twitch. All they should and can do is make it as easy as possible for us, by announcing changes, and in the best way not restricting what we want to create.
Unless 3rd party development is something Twitch/Amazon want to specifically focus a lot of resources on, then demanding those resources will only hurt 3rd party developers on Twitch.
