It should be possible to include templates that are stored on Commons. Just like we can do with images! This would be for centralized templates. Examples would be:
- Templates for interwiki links (interlanguage links); this would make the interlang bot activity almost unnecessary. Solved by Wikidata
- Templates with current information like software versions, etc.
There is much more application range, of course. This would help reducing redundancy! Currently all the work that is the same in every wiki has to be done xxx-times. With template inclusion from Commons enabled we only have to do that once. The template names could be in English, or in the language of the creator (who comes first...).
