I would say that’s probably about as much as you would want. The best technical writer I ever worked with went from basic computer skills to becoming an expert at deploying and configuring the database software we developed on myriad infrastructure. The newcomer’s mindset helped make the writing wonderfully approachable for anyone to read.
The process was always something like: 1) Learn how to do the thing, but ask really good questions along the way (I often reconsidered some of my own design choices from those questions) 2) Use the gathered information to write about doing the thing.
