The permission system in UBB.threads is one of the most granular of any forum title available; an admin can customize each forum down to some really fine grained options which other products just don't allow.
This can be daunting to some admins, which is why the forum template and copy permissions options were instituted; but it's not like someone is in there on a constant basis adding new forums and categories.
We will not be "streamlining" this process, ever, as it'd remove these options. The forum template and copy permissions options already trim time when creating new forums and categories, by allowing you to set a common set of permissions so you don't have to customize them every time you want to create a new forum.
