Debian (an every other distro I'm guessing) has been doing it like this
for a really long time. Everything is versioned. When the distributor
makes packages, they build and ship all the packages together: sources,
binaries, .el, .elc, and so on.

When a user installs the packages at a later time, they don't have to
download and install the whole set. A user installs "emacs" version
"abc". The version string includes the upstream version that select a
specific emacs release AND the packaging version. At any later point in
time the user can install "emacs-el" version "abc" or get the sources
for emacs, again at version "abc". The identical version numbers
guarantee that they're downloading packages the distributor built at the
same time as the "emacs" package the user has already. It works.
