(I have no idea if this is actually practical, just an idea)
**Feature summary** (what you would like to be able to do and where):
If a translation is outdated then any translation variables should be substituted based on the definitions in the tp:transver rather then the definitions in the latest version of the source text
**Use case(s)** (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
MediaWiki.org has a lot of pages where someone renamed tvars from string to digits, and then didn't properly update translations. (No, they shouldn't do this IMO, but I have no control over what others do). The result is broken pages that link to literal translation variables.
**Benefits** (why should this be implemented?):
Pages render less broken. I just fixed an instance of this in https://www.mediawiki.org/w/index.php?title=Translations:Wikimedia_Apps/34/ar&diff=prev&oldid=6603402, when some unrelated vandalism combined with T367934 brought it to my attention
