Provide function to get the administrator role ID

Wondering what the use case is, generally speaking we should be checking permissions not roles

The tickets that reference this one would probably use such a function.

In my case, I wanted to customize which roles auto_username module acts on. The problem with using permissions is that the administrator role always has all of them. If I made a permission which would cause users to be excluded from auto_username, the administrator role would be excluded even if I don't want it to be.

It feels like your permission is inverted. Permissions should grant access to something rather than revoke it.

A permission could grant a user the ability to avoid having auto_username change their username. But perhaps we actually want administrators to have auto-generated usernames. So we make the permission mean that they have access to auto_username generating their username. Now we can't choose that administrators customize their own names.

The function I'm asking for is useful in the context of having methods like ::hasRole() and ::getRoles(). On the same basis it could be argued that those methods should not exist because everything should be done with permissions.
