Apparently, it's not a priority. :/
Steam is a cancer. Very few realize though.
honestly the one good thing I can say about steam is that it had such poor customer service that it drove me off the platform early and - in part - started my path of learning about DRM free gaming.
It sucks to be treated as a second class citizen by so many publishers but I have zero regrets about leaving steam behind and no longer buying any games with DRM.
Loved Don't Starve, would love to play online with friends. As others have said I'd even buy it again at retail here on GOG, but for me at least I'm not going to be playing it via steam even if someone gave me a copy for free.
Always sad to see a developer go this route :(
