You hopefully saw that I linked the article size guidelines above alongside the 21,000 words figure. That page is only 1700 words, so feel free to give it a read and see if it soothes your curiosity for why we have them (definitely feel free to ask if any claims made seem dubious or terminology is unclear).
Keep in mind that Wikipedia is an encyclopedia and that this singular “article” represents nearly 50 pages of prose in 12-point, single-spaced print – the size of a novella. Wikipedia articles are meant to be encyclopedic treatments of their subjects, not dissertations on them.
Edit: just checked, and the “Download as PDF” of this article is 153 pages long.
