In terms of #2, there's actually a ticket that I put in a while ago for a
shared data cache.
But, I recently realized that the common pattern is to literally map every
line in a file as a separate resource. We've had the same issue with
firewall rules, etc... for quite some time. So, the most "user obvious"
thing to do is to let everyone keep throwing resources everywhere but be
able to mark them explicitly as being 'lightweight' or 'ephemeral' or
This was really solidified for me when I started passing around hashes to
be able to collapse my augeas command into a single run. I thought about it
and realized that's a LOT of work to get around limitations in the
