As a writer who has had to deal with suggested changes by editors extensively, I would say that it is weighted toward the user experience of the _reader_, not the user experience of the person who has to actually accept or reject the changes. If I am the person who has to incorporate these suggested changes into my document, having to delete two segments, one on either side, for each change is not an ideal experience. If this type of formatting does become adopted, I would recommend that the process of accepting or rejecting the change be done programmatically, rather than manually. I could envision a small utility program that is fed a file with this text format and allows the user to interactively accept or reject the changes without having to do the deletions within the file itself.
