I believe the idea behind this is to keep the web hook payload consistent with he actual users endpoint. The web hook is just doing the dirty work for us so we don’t have to keep paging the API.
I haven’t done any work with the Twitch web hooks yet, so I am not sure exactly how they impact the use of the rate limit. However, you could always use an app access token, or use the more traditional OAuth token to increase the limit to 120 requests per minute regardless .
