They’ll streamline better over time. These open source WINE frontends/orchestrators may as well have 2 eras, before and after Proton. Before Proton they had little developer interest so development was slow. After Proton, influx of users and more developers interest in working on open source Linux gaming tools and Lutris rapidly got better and Heroic popped up. PlayOnLinux got left to historic obscurity in the history of Linux gaming

So I’m not concerned about Steam reliance. Everything outside of Steam is so much easier because of Valves open source contribution and the growth of the community. Pretty much because of Valve, Lutris/Heroic/etc became better at a faster pace and will continue getting because of what Steam did for Linux gaming in the past decade
