As of right now modding has taken a bullet to the gut. Either it will bleed for a long time before dying, or it will get back on its feet in time. In hindsight this move by valve was inevitable, give the volume and quality of mods being produced. Free and easy availability of mods is the only reason why games like Fallout and Skyrim last for years. It is also why people buy these games. Next few weeks should be interesting anyways.
