I asked myself the same question once. Having worked a bit on this before on msft I learned that builds, just like other dev tools, need constant improvement as complexity increases. Faster builds, customization and allowing scripting, parallel building, etc... It's one of those things taken for granted because it's always been there, like the F5(compile), but It's a tool which can be improved just like any other.
