This sounds like good news. I think moves to stabilise digital goods rights to more closely mirror those of physical products will increase consumer trust (gamers win), lead to more risk taking in purchases and so more upside to taking creative risks (devs win), and a healthier long term store (distributors/platform owners win). Enforcement of these consumer protections on digital stores is a great thing for everyone; it's almost as if, many years ago, people worked out that consumers who felt safe to hand over currency for goods because they knew they weren't going to get scammed made trade easier and everyone better off so they made up a set of rules that best protected equitable exchanges. Then someone decided moving from buying a box (with a load of 0s and 1s in it) to getting that product down a pipe (built to send those 0s and 1s) was a great time to try and roll back those consumer protections. And now there's all this worry about how to avoid being scammed by bad products, how products should be restricted from even getting onto infinite digital shelves to protect people, and so on.
I think this is an idea whose time has come, as I've commented before while explaining exactly how this stuff is meant to make consumers feel safe handing over their money. GOG gives you refunds for 30 days (although they could do more), even EA have some refund policy in place for not-Origin; it's time Steam changed to their "argue with a CS rep using a support ticket and maybe we'll refund you" policy.
