How to handle different bl_info metadata categories?

The category in bl_info is set to Object in the __init__.py file in the randomiser folder. This is used by materials, transforms and geometry which may have different categories so how do we handle this?

If it's simply a way to filter the add-ons then it may be an unimportant issue, but if it affects which categories we can operate on then we may need to re-think this.
