Usually, yes.  Sometimes there is a package foobar-8.1.0 and additional
foobar6-6.7.1, foobar7-7.9.12, i.e., installing foobar installs the
current version (8.1.0) but separate packages are provided for older
versions and you can have all of them installed in parallel, but that's
mostly done for libraries where some other package only works with
version 6 but not 7 or 8.

And from a distro packager's point of view, the additional
user-convenience of enabling users to compare emacs version X against
the current version surely doesn't justify the added maintenance costs.
