Deletion of Geocast

Comment: Subject of quite a few academic papers, see https://scholar.google.com/scholar?q=%22Geocast%22 Google scholar, and is discussed in multiple published books, some as recent as 2018. Seems to be a relatively established term/concept. The current state of the article is not to be taken into account when discussing deletion. It does pass  in my opinion
Stance: keep
