GOG previously said they planned to look closer at Linux, and that it was the next major frontier - and they're now working towards GOG Galaxy on Linux.
Like the other comment says, it’s closer to Heroic Launcher. It is owned by GoG, but it also interfaces with other stores. Valve will/would never do this.
