Please remove Russian fallback for Ukrainian language. It is not needed now.
- Patch https://gerrit.wikimedia.org/r/290362 removes "ru" from being a fallback for "uk". This means whenever a Ukrainian translation is missing, Ukrainian users will not see Russian translations as fallbacks any more. Instead they will see English.
- This change will also break existing links to special pages, parser functions and other magic words in cases where a Russian keyword was used in a Ukrainian wiki. To avoid this, the Russian keywords are added as aliases in a series of patches (see https://gerrit.wikimedia.org/r/#/q/status:open+message:Russian+Ukrainian for the open ones). These are not fallbacks, but aliases. Ukrainian users will never see this, except when a Russian keyword is manually added to a wiki page.
