Feature summary (what you would like to be able to do):
Allow for MediaWiki wikis like Wikipedia to be installed as a progressive web app.

Steps to reproduce (a list of clear steps to create the situation that made you report this, including full links if applicable):

• I can add Wikipedia as an "app" in Microsoft Edge or Chrome by using the "Install this site as an app" feature of MediaWiki.
• Unfortunately, without progressive web app, this usually just adds a link to the apps list that loads the site upon opening.

Use case(s) (describe the actual underlying problem which you want to solve, and not only a solution):

• This could allow for a more tuned-down experience of wikis like Wikipedia. Additional features, like downloading articles we encounter on wikis for future reference, could be added to these progressive web apps.
