Debian does as well.  What Rob is saying is that *if* you want to use
the Emacs provided by Debian, then the choice of which flavor (and
version) you get will apply system-wide.  If that's not good enough for
you, then you can install your own build of Emacs in the usual way, and
it's very easy to do so.

All my Debian boxes come with "Debian's Emacs" installed, and then most
of them have a few other versions built locally for my own personal use.

AFAIK he wants:

- To eagerly compile the `.eln` files for the third party ELisp packages
  installed system-wide using Debian's package manager.

- That every time Emacs is run as part of
  (un)installing/building/testing a Debian package, that Emacs should
  not write any file under $HOME/ (or ~$REALUSER/ either).
