I wholeheartedly oppose this not just for the systems I work on, but for the overwhelming pressure this will put on EVERY app. The rate limit alone is abhorrent, never mind the 3 short weeks to prepare what, for me, amounts to 20 separate microservices. Twitch keeps holding Developer Day after Developer Day, BEGGING people to develop apps which integrate with the Twitch APIs, and this will kill almost all of them.
