That's exactly what I don't like: Classes that have other primary tasks 
but act as just another Action provider. See below.

If they are different, they are useful because they provide Actions in a 
way the ActionsTool can't.

If they are just another Action provider, the only benefit is that we 
can store the Actions inside of related tools. The price for that is high:

- additional action providers add complexity to the site

- in many cases it is not obvious where to store or find an Action

- defining the order of Actions is harder
