MediaWiki used to handle this inconsistently: multiple links for the same
language where shown in the sidebar, but not recorded in the database. This
inconsistency was fixed a few months ago - now, only one link per page can
exist. I suppose that's why the template no longer works.

Someone's bug is someone else's feature... Anyhow, on fr-ws they already have a custom menu on the left to link with other wikimedia projects ("Compléments") which is loaded by: https://fr.wikisource.org/wiki/MediaWiki:Common.js

Example: https://fr.wikisource.org/wiki/Victor_Hugo

If you want to add a similar menu for editions then it should be compatible with:
https://www.mediawiki.org/wiki/Extension:DoubleWiki

I'm not suggesting to always great a work *page* on wikisource, even if there is
only one edition in that language. I'm saying that there should always be an
*item* for the work on wikidata, even if there is only an item for one edition.

Sorry, I misunderstood you. Yes, I agree it makes sense to create an item for the work on wikidata.
