Well, I'd disagree with you on a few things.
For me, it's not "doing great". Yes, the game itself looks excellent, but it's been years for the devs to make this amount of progress. In that time, they've been simultaneously and concurrently working on other projects (including that god-awful Halloween trailer thing).
The second idea I'd strongly disagree with is: "If you want it, support it."
The problem here is that Patreon is a very interesting way to receive funding. Just because a dev receives patrons doesn't mean they're incentivized any to produce content. In fact, because devs are being paid monthly, it's actually BETTER if devs produce content more slowly to eke out more money from existing patrons, and to add new patrons once the newcomers see the current content.
My advice is: set your notifications for the game, forget about it, and play each new release after about 6 months (their update cycle), then forget it again. Does that mean not supporting the game financially will potentially risk causing the game to crumble? Sure. But looking at it another way, losing loads of patrons will demonstrate to the devs that this game is far more important than any of their side projects and can encourage them to work on getting out a completed game more quickly and THEN work on the minutiae and other projects once finished. And again, the idea of "supporting at all costs" is far riskier anyway (even in simply saying that phrase too, it's rather obvious). I'd rather take the chance that this game dies than pour lots of money into it and have it flop anyway. There's always another game.
