This sounds like an interesting idea; I have been meaning to use tags more. However, I wouldn't want to exclude the possibility of using this functionality in a non-programming context -- i.e. collaborative editing of arbitrary text documents -- which would argue for approaches based on storing arbitrary text context using Emacs bookmarks or custom text searches. Perhaps the new functionality could involve a choice of more than one new Org link type?
