MediaWiki Application Rationalizations

Application Rationalization is a term used in economics to describe the process of transforming an organization from one that maintains an ad-hoc software portfolio to one that does so based on a set of published rules or rationales. The goal is for the organization to avoid obtaining and maintain multiple applications that do the same things.

So.. How do you justify the use of MediaWiki to your management? Application Rationalization provided by User:Revansx "A fully-featured MediaWiki site is uniquely suited for organizations and projects to digitally transform their internal processes and automate the management of their knowledge and records by providing an in-house 'Single Source of Truth' (SSOT) environment for applying a 'Model Based System Engineering' (MBSE) approach to developing electronic processes which generates all artifacts (records and knowledge) as in-page data; and enables the tracking and monitoring of any process metrics the organization seeks to optimize."

Scientific purposes
I've focused on these arguments, which occasionally work. For a reference encyclopedia of scientific work we want to have:
 * Footnotes (to ground our work/findings in previous work which we don't need to read in detail)
 * Categories (for searching within concepts, not for a known string)
 * Equations in a standard (TeX) format
 * Redirects (for alternative names/spellings/languages)
