I don't really see how a Steam workshop would get the mod creators to update any faster or do anything that a mod manager like Vortex doesn't already do. Everyone who uses mods should know that they do so at their own risk and that updates can, and probably will, break their mods at least temporarily. It's a known risk, not just for this game but for any game that you mod, including those with a Steam workshop. You're frustrated, but that kind of thing goes beyond what the devs, should be worrying about.
