It does at least add a useful feature: being able to state a location to search from. The Wikipedia page (unless there is one other than https://en.wikipedia.org/wiki/Special:Nearby that is more flexible) will only work off your current location, which is completely turned off on my work machine. Also upon checking on my phone, even with “desktop site” forced, the map looks to be an additional feasure too.
You can put the coordinates of any location in the URL. One way to get that is in google maps, when you right click and click on the coordinates. Paste it where the coordinates go in the URL and remove the space after the comma.
It appears to limit itself to 50 results though, which only got me results up to 930 m away from the location I picked near me.
