Well, it's what we have currently. We could add support for gcc-compatible depfiles, but then you're stuck with only new versions of DMD or LDC if you use CMake. Adding support to CMake and Ninja is much easier than upgrading the compiler since they're much smaller and more easily upgradable (fewer moving parts, lower chance of getting subtle new behavior[1], more reasonable to expect or ask users to have an up-to-date version, etc.). Getting the -M flags recognized and implemented in DMD and LDC are good goals to shoot for, but we're constrained by the tools we have available… --Ben [1]CMake is (ideally) loud when this occurs through its policy system.m
