I think the most important part of this is adding ways to support a developer. We aren’t machines and while sticking to a content schedule is nice, the way you’ve laid out hard numbers is just not how it works when you’re a creative.
Sometimes people want to support a creator while they’re working on a long-term project regardless of the final result. If the supporter is unhappy with the release cadence they can always unsubscribe and resub later if they want to.
