However I'm a big fan of (team) survivalgames I don't think it's worth it.
Survivalgames has been removed due to the lack of players playing it, hence why I don't think it will make its return anytime soon. It might look nice for now but after a little while it will get a little boring again so the playercount will decrease (again) this means that survivalgames does not have enough players to fill your game with. I think they should keep it as a featuted gamemode for now, that way it remains special if the community chose it to become the next featured gamemode and it keeps the playercount alive.
I think they should consider it if the player count increased to over 8k daily players, because then there will be much more players playing it.
If you want to play survivalgames, feel free to vote for it :)
