    // - Keep version reqs low, ignoring compatible normal/build dependencies
    // - Take advantage of latest dev-dependencies
    // - Rollup safe upgrades to reduce CI runner load
    // - Help keep number of versions down by always using latest breaking change
    // - Have lockfile and manifest in-sync
