Yes, they do.  When the Debian emacs pacakges move from a 27.x version
to a 28.x version, upgrading will just move you to 28.  You can't have
more than one version of emacs installed via the packages right now.

(You could in the past (we had emacs25-nox, etc.), but we "unversioned"
 them for now because, in part, upstream backward compatbility with
 respect to anything "substantial" has been excellent for a long time.)

That's not allowed (and that in particular never has been in Debian and
(I assume) derivatives).  e.g. installing emacs-nox will automatically
force out/replace emacs-lucid if the former was installed, and then all
of the .elcs (and .elns if we go that direction) will be automatically
regenerated during the switch.
