Actually that, to me, is a negative right now. Since there's no way we'll make LTO the default in the foreseeable future, people starting to use it like that is just a bad bad thing. So really, the main advantage of LTO would be any actual optimizations it can do. And call me anal, but I want *numbers* for that before I merge it. Not handwaving. I'm not actually aware of how well - if at all - code generation actually improves.
