We actually use a pipeline that runs compilations by recording & replaying past snapshots of our codebase. The record logic we have don't retain access to directories in its required inputs set, as clang stats lots of directories when performing include search etc, which are not ~never needed for the compilation (apart from the one that contains the actual files).
