 12  # Incremental compilation is useful as part of an edit-build-test-edit cycle,
 13  # as it lets the compiler avoid recompiling code that hasn't changed. However,
 14  # on CI, we're not making small edits; we're almost always building the entire
 15  # project from scratch. Thus, incremental compilation on CI actually
 16  # introduces *additional* overhead to support making future builds
 17  # faster...but no future builds will ever occur in any given CI environment.
