Previous task: T165175: Support communications around the preprocessor fixups
Here are some action items for me:

1. Listing somewhere the editors that did most fixes;
2. asking them how they learned about the work that had to be done, to understand which venue was more effective for communication;
3. Some community members found out about https://www.mediawiki.org/wiki/Parsing/Replacing_Tidy/FAQ#Volunteers_available_to_support_this_effort and signed up - how to keep them involved? How to make others list themselves there?
