"Trust (customers) but verify (games)" works but at the cost of Steam/Valve having to implement either human verifiers or AI verifiers.
This will cost with low ROI.
If Steam is indeed customer focused, they might but doubtful.
Every major gaming outlet and studio has at one time or another decided to try to play chicken with their customers. This never goes well. Historically Steam has been pretty skilled at not finding a hill to die on so one would assume they'll avoid the obvious blunder of ignoring users preferences here.
This doesn't feel like something I want Steam to do. Valve should not both host the games, profit from sales, and decide winners in the market themselves.
This is really a call for games journalism to step up and try to innovate. Human curators with taste, and a number of them with different mindsets who people can find one that meshes their own, is more important than ever.
