(Please keep commons-l cc-ed, not everyone is subscribed to mediawiki-i18n. :)
Could the extension can, or be tweaked to, help with our other
multilingual content? […]
LS is already deprecated and should be killed at least for templates (multichill told me very few if any still use it, right?);
Well, it has more than 3.7 millions transclusions… See also < https://commons.wikimedia.org/wiki/Category:Internationalization_templates_u...
Just asking: would it play nicely with our AnonymousI18N script?
<https://commons.wikimedia.**org/wiki/MediaWiki:**AnonymousI18N.jshttps://commons.wikimedia.org/wiki/MediaWiki:AnonymousI18N.js
If it's what I remember, that would be superseded.
AFAIK, AnonymousI18N handles the following :
* Language selection → Handled − that is kind of the purpose of the Universal Language *Selector* right ? ;-)
* Language suggestion, based on « data from cookie, referal url & browser settings » "referal" means that AnonymousI18N can detect that your are coming from it.wikipedia.org, your interface should be in Italian → What about ULS ?
* Language “uselang” persistency, regardless of the previous Meaning, if landing on Commons from a URL with ?uselang=fr (obviously from templates on projects, but also from links everywhere [people like me who always tweet/write links with a uselang ;-)]), the ?uselang=fr is set for all outbound links, meaning language persistency.
→ ULS does not appear to do that from my test on TranslateWiki. (Arriving from https://translatewiki.net/?uselang=it, interface in Italian ; clicking a link, interface in French)
