Show outdated (not missing) i18n strings

My website makes heavy use of translations. All pages are available in 18 languages, and so are the i18n strings.

For the regular pages I’ve found a way to display whether a translation is outdated against the EN original.

Is there some similar possibility for the i18n strings? I know the `–i18n-warnings´ flag but it only displays missing translations. Is there some way to highlight i18n files which are behind the EN original, or even the individual strings? That would help dynamic websites to improve strings and alert if this breaks some existing translations.

Thanks for your thoughts!


This is problematic I think. Everything I think of has major caveats.

Another thread is kind of ongoing about maintaining translations…:

Edit: by the way, nice shortcode!
