If they wanted to move towards less curation, then it seems counter to them creating tags, "recommended for you" games, steam curators, discovery queue, or their two new customizable curation panes on their homepage, and more, all in the past year.
Steam is very visibly and actively trying to improve curation, and despite being very poor at it previously, they have very much improved rather quickly.
The entire point of tags and Steam curators is that Valve doesn't do the work, "the community" does. They're not trying to improve THEIR curation, they're trying to give users the tools to do it themselves.
