My vague recollection is that the past objections to doing this sort of
thing were because the semantics are not exactly the same -- I think it
had something to do with the way that diff.el would visit each half of a
context-hunk in turn, whereas diff-mode would visit subsequent hunks
instead (or maybe it's the other way around :-) -- and that some users
might object to the change.

My feeling before was that it's all a bit silly and arbitrary, and the
gains from using diff-mode everywhere far out-weigh any minor
compatibility concerns like these: diff-mode is just _so_ useful, that you
really, really, want diffs of any sort to be using it where possible.
