Something which is a coherent whole and is currently in one place will
be split amongst two, or several, places, leaving it less coherent.

Nothing, of course.  But it will be more difficult, less pleasant, more
frustrating and more error-prone.  Maybe not by a lot, but noticeably
so.

There were several bugs several years ago caused by the introduction of
prog-mode.  And there are now features in major modes where it's not
obvious whether they're implemented in prog-mode or the major mode
itself.  Finding that out is extra work.  That's fragmentation.
