Hello,

We have a proposal to make small adjustments to the MediaWiki database policy which would make abstract schema an explicit requirement.

Abstract schema was approved by TechCom in https://phabricator.wikimedia.org/T191231 and now core and all WMF-deployed extensions have migrated to abstract schema.

You can find the proposal in here. Please take a look and comment:

https://www.mediawiki.org/wiki/Talk:MediaWiki_database_policy

If there are no major objections by the end of August 2022, I will codify this into the policy.

Best
