Is it considered acceptable now to produce a service or API that hardcodes wiki-specific parsing of certain wikitext or HTML patterns in certain wiki pages (such as the "On this day" section of the main page of one wiki)? I'm confused by the status of things and after my comment https://phabricator.wikimedia.org/T143408#2919000 I see little effort on finding solutions potentially able to scale to all our projects and languages (which I assume to be the mission, see "globally" in https://wikimediafoundation.org/wiki/Mission_statement ; please point it out if this assumption is incorrect). It might be that wiki-specific parsing hardcoded in MediaWiki/Wikimedia code is actually able to scale, if written correctly; a comment on the association patch seemed to imply so. This would be a very surprising finding, and one which goes against 15 years of experience, so if we have some examples or evidence of this it would be very worthwhile to point them out. Nemo
