Why would warning be required in that case? Red links aren't bad.
Maybe it could be set in preferences whether one wants the warning displayed or not.

Red links not bad? Maybe for article links, but what about files? ;)

The point is you wouldn't need to check "Links" (on file pages) and esp opening "What links here" (on all other ns) when deleting other pages just to see if the page you want to delete is linked to.

If linked to you may want to do some action e.g. remove the displayed image, etc.

Can't see why this is not very helpful.

I still think this would be useful. Maybe it shouldn't be a warning but an info?

I would even extend this and add it to page moves as well.
