I mostly dislike how this is adding nothing new to Discord syncing subscriber status from Twitch or Patreon; doing that assigned the subscriber who connected their accounts a role, which could then be used for permissions to access content. This is all that a Discord Subscriber gets (role access to exclusive channels), besides "Premium Emotes", which is nebulous in value.

Having to use a fiddly separate system is a pain. I've got more than one membership where the whole community and content is on Discord and the Patreon exists solely to manage subscriptions; having that built into Discord seems like an obviously better alternative.
