It will be better if you can switch your own gamemode and make it so that you CAN NOT change other ppls gamemode just ur own, this will help creative in a HUGE way, as you have more options on hat to do, for example so that u dont accidently fly (this bugs me alot when im tryna do the swimming trick with the Elytra for rp's) So I really hope you are able to do /gamemode survival /gamemode Spectator and /gamemode adventure This would be really cool for rp's and some other things
