Chromium once supported unity builds. For me it speeded up builds from 6 hours down to 1 hour 20 minutes on a Windows laptop. And Chromium tries to make their headers reasonable.
Chromium eventually dropped support for such builds. At Google the developers have access to a compilation farm that compiles within like 5 minutes. With such farm unity builds makes things slower as they decrease parallelism. So Google decided not to support them not to deal with very occasional compilation breakage.
