There used to be [1], but alas, the times, the times ;-)

And in practice. Your "But..." somehow suggests someone is trying
to prevent the user from doing that. I wouldn't touch such a
distribution :-)

Suppose I hear about this nice function `dired-jump' I do C-x f and
find out it's in `dired.el.gz', which is in a system location, and
thus read-only. I write it to my own location, which for me is in
~/.emacs.d/lisp, change that to my heart's content.

Due to how `load-path' is set up, this modified version takes precedence.
I take over responsibility for this one file and let the package manager
(or, in my case, Emacs's "make install") to take care of the other
7878 files. The package manager (or "make install") won't touch "my"
file.

That would be the "low profile" approach.

Of course, if I want to keep that up for a longer time, I'd clone
the Emacs repo and open a branch there. Or download the Emacs Debian
source package, if my aim is to package my personal changes to Emacs.

Hacking "in place" things which are installed by a package manager (or
by an install script) is a recipe for pain: it's you against the computer.
The computer always wins :-)

Hm. I do, too, but I always do "make install".

Sure :)

Same with me, that's why this situation is "interesting" :-)
