I could not find any new bug report.  Perhaps the BTS discovered I was
replying to an existing bug.

I'm BCC:ing this to submit@bugs.debian.org, lets see what happens.

One solution would be to modify emacs to look for, before default.el
and site-start.el, a /usr/share/emacs/debian-lisp.el and have a
/usr/share/emacs/debian-lisp.rc/ directory which corresponds to
todays' /etc/emacs/site-start.d/ but is managed entirely by Debian
packages.  The files should contain the minimal amount of code
required to get a package up'n'running, and should assume the rest of
the package is installed.

Then /etc/emacs/site-start.d/ can be dedicated entirely to site
customizations, instead of being something where debian packages write
to but is unable to modify or remove in.  Having debian packages write
to something called "site" seems confusing to me, Emacs uses that term
for site local modifications.
