I am helping the people who are writing in the recently created N'Ko Wikipedia to learn the technical sides of contributing to Wikimedia projects. One of the repeating issues that we ran into is that they cannot add sitelinks to Wikidata for some articles: the first articles that they created are, quite naturally, basic famous items about things like countries, planets, philosophy, etc. Some of the items about these popular articles are protected. These users have hundreds of contributions in their language and in the Incubator, but not on Wikidata, so they couldn't add a sitelink.
I asked to give them the Confirmed right on https://www.wikidata.org/wiki/Wikidata:Requests_for_permissions/Other_rights , and the right was given. It would be even better, however, if it was given automatically and the step for requesting this manually wasn't needed. A user who has more than a hundred edits on another wiki is probably trusted enough to add sitelinks. Given Wikidata's special nature as a central data repository, there should be mutual trust between projects.
Obviously, this applies not only to the N'Ko language, but to all languages.
I'm not sure that this can be done in core MediaWiki itself. If not, perhaps there could be some kind of a bot that grants these rights to users, so that they could start contributing transparently, without having to request the rights.
