Unluckily, yes, this have spread in ITW a lot.  The api is being dirty by non-private utility 
methods which
  - should be private
  - should be tested

I would probably like to set some kind of rule for this to future. To test such private methods via 
reflection stub. It will move test "api" issues from compile time to runtime, but by retrospective 
look, it is probably worthy.


Options?
