      with LU-18818 tunefs.lustre takes much longer now.
      for example, conf-sanity/73b took ~20s before, now it takes 600+s on tmpfs backend.
      in AT it was ~100s before, now 700+s.

      AFAIU, this is due to MMP enabled as adding EXT2_FLAG_SKIP_MMP to open_flags_rw fixes the issue. I understand why MMP was enabled, but sure this behavior will be found confusing.
