If anything I think PC has been a prototyping or proving grounds for technologies on the roadmap for consoles to adopt. It allows software and hardware iterations before it's relied upon in a platform that is required to be stable and mostly unchanging for around a decade from designing the platform through developers using it and recently major refreshes. For example from around 2009 there were a few cross platform games with the baseline being 32bit/DX9 capabilities, but optional 64bit/DX11 capabilities, and given the costs and teams involved in making the kind of games which stretch those capabilities I find it hard to believe it'd be one or a small group of engineers putting significant time into an optional modes that aren't critical to the game functioning and supporting them publicly. Then a few years later that's the basis of the next generation of consoles.
