My use case involves trying out some "Emacs as a Service" types of things
under various versions/builds of Emacs.  In honestly, I'm not sure the draw
toward docker vs native package install (or self-build) for day-to-day
use.  For experimentation (perhaps including try-before-you-buy ;) of a new
Emacs Version) it's quite handy do delete the container and know that your
base system has whatever system libraries it had before, all at their
previous versions and so forth.

You would still need to git pull and rebuild manually in the container if
you want something newer than what's current on Dockerhub or whathaveyou.
 I think it's more usual to update the image that use it as a spring-board
for self-building within the container, but my experience is rather limited.
