From what I've seen and experienced, schemes get invented and they change to suit community. It seems to me that it is not a specific person changing it, changes appear when enough part of the community try these changes, like it and accept it.
The great example of this is Roper scheme which had/have enough discussions and ideas how to improve it but still, the "community" seem to have its peace with the way Roper is now and doesn't want to change. (Even though many of these ideas may be good ones)
