Given how deep into Valve's ecosystem I am at this point I'd probably end up eating the cost rather than throw out my library. That said I'd shift a lot more of all future purchases to GoG. Gabe was right in his assessment of things being a service issue and Steam provided the best service with almost zero worthy competitors, so I was able to overlook the DRM thing, but if that service starts to deteriorate then people will start turning elsewhere.
