Template talk:Media link

"This template should be used in main articles only!"
Any reason for this? The template's original proposal doesn't specify any. Image displays aren't forbidden outside of "main articles" at all, so why would direct links to these images be? It would be useful all the same to have a file's usage shown on its corresponding page from across all of the wiki, or, at the very least, other mainspace pages. As an example, several files are linked to from the summary section of File:Mario.png and they should appear on their own pages as being used on File:Mario.png. 14:56, June 18, 2023 (EDT)
 * Yeah, I'm not seeing the reason why we can't use it outside of mainspace. People have been using them on file pages no problem. 22:55, September 5, 2023 (EDT)
