Hi lubben.jan,
I wouldn’t worry about GameScape going away, it will continue to exist for a long time, and continue to be free. The way it’s built it has very little overhead - and I use it every week personally. 
However, feature development has been frozen on Gamescape for the immediate future. I don’t have the bandwidth to work on building new features. I’ve explored open sourcing it and seeing if someone wants to take over extending / expanding it but I haven’t gotten any takers yet. I may occasionally add new features if I have time but probably not for at least six months.
