The way it works is that every tag has a "data item". This is the one for natural=isthmus, for example: https://wiki.openstreetmap.org/wiki/Item:Q19327 Of course, you're not expected to find this numeric URL yourself. You can get there from the wiki page for that tag by clicking on a "pencil" icon next to the description in the infobox, or by using an "OpenStreetMap Wiki data item" link that appears in the left-hand menu on every page that has a data item associated with it. The idea behind data items is actually quite similar to how templates on the wiki work: There is a number of possible properties that you can fill in with information. The properties which are currently available are mostly identical to the ones used by the templates: Whether the tag can be used on nodes/ways/..., links to related/required/implied tags, an image, and descriptions in various languages. If some information is omitted from a wiki page, the infobox will pull it in from the tag's data item. Otherwise, the information written directly on the page will take precedence. A potential benefit of data items is that language-independent information does not need to be manually copied to each translation. And while software like Taginfo has been able to extract information from the wiki for a long time, the hope is that this kind of extraction will eventually become easier thanks to data items. I do not believe there has been a community decision to stop adding information directly on wiki pages. So the other wiki contributor's edit was probably premature. Of course, though, the current situation with content duplicated between data items and wiki pages isn't really ideal. But there's probably still some work left until data items can fully replace the existing systems (updating data consumers, plus working on usability and documentation).
