Code review comment for lp:~robert-ancell/mir/frontend-class-renaming

It's not a rule; it's a convention. And any convention which results in trivial un(der)used classes should probably be changed, or at least bent. As I said above; "If we need to increase abstraction again later for more mocking, then that's an exercise for later".

I feel that Mir has a growing problem with its code complexity out-pacing functionality. That's a particular concern for our ability to maintain and enhance the code. So any successful attempt to simplify things should surely be welcomed.
