..like Steam does? Because these "mega-updates" where dozens of games all get updated at once, putting shortcuts all over your desktop, could only happen if GOG itself is updating their games.

ofc not , the ccp's ministry of truth first have to accept the changes and censor out everything which could hurt many gamer's position in the party

Oh, it does.

It's just wildly vastly underdocumented. I've seen obscure window managers for Linux with better documentation and there isn't even a public facing link for a developer login nor a visible point of access.
