Debian dropped their numbered packages to avoid bug reports for very old
versions of Emacs, see e.g.:

    "plans to finally drop our emacsXY binary packages, and just have a
    single version of Emacs in the archive, so that we no longer have to
    deal with bugs due to someone still having emacs21 installed
    (David’s idea; Rob’s implementation; Sean’s mostly-helpful
    comments)"
