I would say any buffer that has certain major mode, e.g. 'archive-mode' or 'tar-mode'.

Yes, it appears readable, but dabbrev still comes with various "useful" binary data. Perhaps another approach would be to not search for abbrevs in hidden text, but I don't know how that is implemented internally and if it would be easy enough.
