What if instead of "gather_facts: force" we develop a mechanism that is
simple in nature like:
gather_facts: hosts:all
gather_facts: hosts:compute,database
Where we trim the inventory based upon a set of groups? (I just made that
syntax up now, so dont hate me for it...open to ideas) But would that help
satisfy simplicity and your concerns about slow facts and large
inventories?
