I believe I already answered that?
- why would anyone explicitly ask for a feature when they have no reason to believe that feature wouldn't make it otherwise? Previous games had it, Windows version got it, GoG version got it...
- why should a Linux/Mac build of the game not have the same features as a Windows build, or even a different Linux build, barring platform limitations?
I mean, when players ask for a NoSteam executable, they're not asking for a NoSteam Windows executable, they're asking for an executable that'd allow them to play the game without having to connect to Steam. As developers, you understand the difference, players don't necessarily. It's weird that you did the work to appeal to one category of players, but not the other, based on a technicality
