		In your summary, you state "The main disadvantage of using the internal access modifier is that you can't easily unit test such a class".
		Your entire post builds a complex, messy workaround to this through marking active methods as obsolete and having to wrap tests in "ignore warning"
		pragmas. Yet the whole article misses the elephant in the room: internal classes are implementation details; they should not be unit tested directly. 
		Implementation details change, leading to brittle tests that need rewriting as those details change. Unit tests should test public APIs. If internal code 
		cannot be reached via a public API, then delete it as it has no purpose.
