8-9 months have passed, it is time to progress or abandon.

@Aklapper: I tried to find useful tags to make this task easier to find and avoid being stale for years. Tag names are not descriptive and tag links lead to board which lacks description, so it requires 2+ clicks to find tag description.

• #wiktionary-en is absent (unlike Wiktionary-fr), so i tried #wiktionary and it redirected to All-and-every-Wiktionary. Its subproject list is empty and its description does not tell where language specific tasks must be placed.
• (1) Wikimedia-Site-requests, (2) MediaWiki-Configuration and (3) MediaWiki-User-management are confusing. I suppose they correspond to:
  • phabricator: (1) /source/mediawiki-config, (2-3) /source/mediawiki
  • git: (1) [[git:operations/mediawiki-config]], (2-3) [[git:mediawiki/core]]
  • gerrit: (1) [[gerrit:plugins/gitiles/operations/mediawiki-config]], (2-3) [[gerrit:plugins/gitiles/mediawiki/core]]
  • other: (1) https://noc.wikimedia.org/conf/, (2-3) ???

Doubt about the necessity of this new group, why not requesting for admin flag on that project?
