A plain# `-W <lint>` is dropped for a driver-registered lint once the group is allowed,# which is why `--force-warn` is required.## `DYLINT_RUSTFLAGS` is not part of Cargo's fingerprint, so changing it does not# invalidate already-checked crates. We therefore clean the targeted package(s)# first so the filter actually applies instead of replaying a stale cache.
