    Description

      This new two-phase-drop behavior will be enabled by setFeatureCompatibilityVersion, since it will work in concert with new rollback behavior that is in kind enabled by that command. Upon downgrading to 3.4 feature mode, the code can immediately drop all drop-pending collections. Subsequent downgrades to 3.4 mongod binaries should have no further effects.
