Actually it gives you more to worry about. When something blows below the layer upon layers of abstraction you will be helpless. Ask anyone that tried to find workaround about a bug in a core closed sourced framework. You are suddenly playing code permutations.

I have seen the same with some of my admin friends when they throw config after config in a case where something is not working while the documentation says it works and reality says it don't.

So it will hit the fan less often, but when it hits - there will be more than enough for everybody.
