Based on our testing and conversation [[ https://en.wikipedia.org/wiki/Template_talk:Maplink | here ]], we'd like to see if using latitude and longitude as a valid data entry point—along with a Wikidata Qid for a single point—can be added to the [[ https://en.wikipedia.org/wiki/Template:Maplink | `Template:Maplink` ]] and [[ https://en.wikipedia.org/wiki/Template:Mapbox | `Template:Mapbox` ]].
Unfortunately, there are a large number of [[ https://en.wikipedia.org/wiki/Special:WhatLinksHere/Template:Maplink | articles ]] that use the `Template:Maplink` but are effectively "broken" because they use a single Wikidata Qid for a simple lat/lng point object or are using the incorrect syntax (using `shape-inverse` instead of `type=shape`). This change won't help those 'broken' maps, but it would give users an alternate method in which to use when adding a `maplink` to an article.
Adding in this ability could also greatly increase the amount of articles that would have an interactive map experience, since average editors could easily add them into pages that already have coordinates (and new articles that will have coordinates in them), maybe even using this query as a starting point: https://en.wikipedia.org/wiki/Category:Coordinates_on_Wikidata or even this: https://en.wikipedia.org/wiki/Category:Coordinates_not_on_Wikidata
