Perhaps most importantly, there is the enormous existing codebase written as wikitext templates and Lua modules. This codebase is stable and tested, it has worked in production for years, and it has skilled maintainers. It provides important features, which are used on millions of wiki pages, and which users in many more wikis want to use. In theory, these features could be rewritten as Wikifunctions, but since it took about twenty years to write them in the first place, it may take many years to rewrite them.
