on one hand, i'm a fan of anything that makes it easier for developers of all sizes to sell and distribute new games. on the other, i defo understand the concerns for both consumers and devs if storefronts are flooded with broken shovelware titles. steam offers refunds now, which helps consumers a lot in that regard, and the review system on the store has improved by a fair amount, but devs obvs are still going to be competing for space. that being said, i don't know of many people these days who buy games they've never heard of for anything other than a laugh, so i'm not sure how much more valve could do in that regard. the need for things like tax documents will stop jimmy in 4th grade from using his dad's credit card to upload his 30 minute game maker game, but there are obvs lots of people willing to actually spend the money to make stuffty titles and sell them for a quick buck, as we've already seen on mobile stores
