I am curious about this as well…I just started working with the API recently and all I really need to finish my current project is a simple subscriber count, similar to the ‘total’ from follows in Helix. I don’t really want to take the time to dealing with v5 when Helix seems simpler to work with and v5 is on the way out. This seems like such a ‘core’ element of the API that I am really surprised that it is not available yet.
