What I'm getting at, is that if the inline links are tracked, then we can do something about it, before the linked node is unpublished or deleted, i.e. display a warning, or ask the user to remove the link and rewrite the content of the referring page.
It seems like a fairly important thing, otherwise large sites, might find themselves with lots of broken links around the place.
There is the linkchecker module which indicates to the editor there are broken links when editing the page. But this notice isn't provided until the referring page is editing, or if someone actively monitors the broken link report.
Should a more active solution be patched into linkchecker, or is this kind of inline link relationship tracking something that a new module should do?
