My concern with Island Sanctuary is that its very bare bones in general but has a lot of potential to be something that persists through expansions and gains additional features over time. It's the sort of content I enjoy in theory since I'm very fond of anything involving building and carving out a slice of the game world to call my own. I'd be surprised if it continued to receive updates as of 7.0 and especially if it's anything more than a new seed type being added every patch or two. For every bit of content like Triple Triad that is updated every patch there's many more pieces of content that are simply left behind to gather dust.
