All the things you are mentioning have already happened. The limit of turfs per gang was 5, now it's 3. Only diamond players used to be able to hold turfs, now there are different challenge tactics to allow a greater diversity. There were only 10-15 turfs, now there are 30.
It's pretty obvious that not just anyone can hold a turf, nor should they. If you want to be able to hold a turf, you have to work hard for it.
