@Super Dromaeosaurus: I apologize for not following up on this sooner, but WP:EXISTING states that navboxes are meant to assist with navigation through existing articles, not non-existent ones like several of the ones in the navbox now. That's why I redid the navbox a bit ago (that and the color scheme did not look right). Arctic Circle System (talk) 06:00, 22 November 2023 (UTC)[reply]

From what I see that's not a policy but an essay and it also says a lot of "normally" or "should". I also argued that your changes destroyed the point of the template which I defined as to cover the dialects that each language has. Also you simplified the situation of Gumuțeasca and Totoiana as they're not dialects.
In my opinion we either have the template in its current status or just end it. Your version provides no informative value about Aromanian, Megleno-Romanian or Istro-Romanian while the information about Romanian would be duplicated with this template [1]. To be more blunt, a WP:TFD might be necessary. Super Dromaeosaurus (talk) 08:52, 22 November 2023 (UTC)[reply]
@Super Dromaeosaurus: It probably should be deleted in that case, at least until articles about other Eastern Romance languages are made. Arctic Circle System (talk) 10:00, 22 November 2023 (UTC)[reply]
Only some Aromanian dialects could possibly get articles and only if Aromanian dialects becomes too large (far from being the case for now). The other two shouldn't get separate dialect articles. So that prospect is unlikely. Super Dromaeosaurus (talk) 10:02, 22 November 2023 (UTC)[reply]
