For example, the C# language design committee will, almost to a fault, consider every single little micro-scenario for a proposal and weight them all together to figure out if it's going to be feasible to implement, able to accomplish the goals that the proposal sets out, and if it fits in with the "spirit" of the rest of the language. I think it's a rarity in software to have such care put into the design and implementation process and it's amazing that these things are alive and well within Microsoft.
