Looking at ways to improve consistency across pages (and possibly write a piece of information in one location and reuse it in multiple), sometimes it's easier to embed some minor logic into the markup. Looking over the extensions available on [[Special:Version]], I'm seeing a lot extensions available, but none that really help keep the logic in the markup instead of having to write Lua modules.
Is there a reason that https://www.mediawiki.org/wiki/Extension:Loops and https://www.mediawiki.org/wiki/Extension:Variables can't/shouldn't be enabled for this wiki?
