Yes, but if you have to manage the details anyway I'm having trouble
seeing the value of an abstraction - and having to understand both the
details and the abstraction. Do the tools give you an easy way to
reliably repeat someone else's detailed process without having to
understand it?

I think scaling is the general topic here. I don't scale well enough to
deal with learning a new language/protocol/toolset for every single
configuration setting - and especially with variations per vendor. But
those are the real-world configuration problems.
