A suggestion for role management

Hello everyone, I have a suggestion/idea that if Discord were to implement it, it would make role management a lot more precise and could result in Discord servers being able to expand their field of operation with much ease.          

My idea is the creation of so-called "role groups". These role groups would consist of a number of roles which are attached together in one group, which would then be hierarchically managed by the top role.

Let's take this group of 4 roles for an example (look at link for the roles in question). The role Vacant Game 1 Host would manage the permissions of Vacant Game 1 Banned, Vacant Game 1 and Vacant Game 1 Rostered, and the Host role would also manage the members of those roles. But, the Host role would not be able to change it's permissions, these permissions would be managed by other roles who are above it, but not in a role group of their own. This would be for example, someone with Administrator powers or a Moderator role that can manage roles.

The reason for this feature to be implemented would be to make servers more compartmental, thus leading to more autonomy and less overlap of powers between roles, that tends to lead to messy permissions and unintended use of powers. Also with the current system, if I were to make more than one of the groups of roles, the Host role which is the furthest up on the list of roles would get to manage all of the other Host roles and each one after can manage the other role underneath it, so on and so forth. As a reminder, this feature would not be automatic, but it would be someone with "Manage Roles" permissions that would make these role groups and put the roles in manually.
