hi Matt!
Just to add some color, the possiblity for an admin user to be acting as a regular user would add an extra dimension to absolutely all admin related authorization logic.
Even though that logic is mostly centralized in guardian.rb and /lib/guardian/*.rb, the complexity and bug potential for such a change would be very large, and the necessity of this feature would need need for far outweigh that, which it doesn’t, given the alternatives.
