Can we please specify, what things that could break and what things that should do to acomodate this changes?

@rahmatrhd @mabdh We can merge this. But based on how the decision goes for #171, we should think of the right name for this entity. I think grant is a better name for this instead of access. access can get confusing as the entire Guardian itself is about access.
