The goal of a Wikipedia article should be for a wide audience to understand the basics of something
I don't think this is true. Wikipedia is a collection of knowledge, not a set of introductory articles.
See e.g. the Wikipedia pages on intermediate-to-high statistical concepts and techniques, e.g. copulas).
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
