I think this is a great example of "scratch your own itch". Rarely are frustrations so specific that they don't impact multiple individuals. SEO aside, you're benefiting those who come after you asking the same questions.

About two years ago I started writing specific technical posts that I had to piece together from various sources. Although it's primarily for my own selfish reasons to reference later, I've seen quite a lot of traffic from folks who are trying to find the same solutions. Not too unsurprising, the key here seems to be the more niche a post, the better it performs compared to posts that cover broader topics.
