Of course compile time matters when features like modules provide a significant improvement. My question was more focused in having to work around the compiler by doing micro-optimizations, or avoiding some features that "may be heavy", just because one project will take 65535ms instead of 65000ms to do a minimal rebuild. But at the end of the day, it really depends on the dimensions of the project. In a huge project an improvement from 8 hours to 7.5 hours is greatly appreciated.
