I hope they don't back off the idea completely. There were issues with how this was implemented, but if Valve back off the idea of allowing content creators sell their content on Steam altogether.. then that's stupid.
Their statement pinpoints their failure being in execution, and in messing with an established fanbase, so yes, I think this is far from the last we've seen of this.
They'll probably bring it back with one of their own future releases. So Left 4 Dead 3.
