But the only way to make progress in Linux is to actually post patches that "improve X." This is unlike many corporate environments, where you might need to get somebody's approval before you even start trying. In Linux, there's no such thing as prior approval. Even if you could get somebody to say "this looks like a good thing to try," that would be no guarantee that subsequent patches would be accepted. It's hard enough to get people to comment on actual Linux code changes, i.e., patches. It's almost impossible to get useful feedback on proposals without code. If you posted patches that made significant improvements in build time, I think people would be very interested.
