I'm sure it's ok when utilised by skilled hands. But unlike a lot of tools it's just too easy to get things wrong. Possibly by a lack of good documentation or design. I'm still feeling bitter after seeing it introduced on my last project, a Rails app. Build times went from seconds to 15 minutes. After experiencing that I will make every effort to argue against it's inclusion on my current project (should anyone propose it).
