Could you suggest an amendment? I understand what you are saying below,
but I'm not sure how or if you want it incorporated into this patch.

If you feel this is critical to change (I have no opinion either way),
then I'm happy to send a re-roll once review has stabilized. When do you
plan on finishing your read-through of this v3?

Thanks,
Taylor
