Looks like the developers posted an update basically saying they're not updating this version here anymore and will be working on Steam.

No information on how long this going to take or when and no link. Given the current Steam process, they'll need to submit it through Steam Greenlight (but I don't see it there yet) so hopefully they'll provide an update and a link once they do.
Well, Valve is planning to replace Steam Greenlight with Steam Direct this Spring so even if they're able to put it on Greenlight, it's probably better to wait as Greenligting takes time (and 100$) and they may not be able to make it before Steam Direct comes out.
Yeah I talked to a Steam guy a week or two ago (I'm working on a few games and had a Greenlight question). They're going to replace it with Direct but for now the process is still Greenlight as they haven't worked out the details yet on Direct (like cost). No idea if the Raft developers will just wait for Direct or go through Greenlight right now (but given the popularity of Raft I'm sure it would go through quickly).
I can't speak for the developers but I'm sure they'll figure something out if they're fair (I would). Like if you donated some amount of money for the game in the first place (some percentage of what they might finally charge for it on Steam) you would get a free Steam key to get it from there. The problem with Steam is you can't charge whatever the user wants like here so it's a fixed amount, and the developer hasn't said anything about what that would be or how they'll handle itch.io users. I'm sure that's part of all the logistics they'll work out when they move to Steam, it's just a matter of time.
