Right, that's similar to what I do by adding the git clone as a symlink
in .../elpa/packages.

That's indeed my experience as well.

Why loaded twice? Do you mean because package-initialize does it once
and then borg-initialize does it a second time? If so, then I'd suggest
to change Borg so it doesn't do it (and relies on package.el to do it
instead).

Currently I deal with this by making the symlink point to the
.../<pkg>/lisp rather than to .../<pkg>/lisp. This also works for cases
where git clone gives me a large package which includes some Elisp
support package inside (typically the git repository for a new
language, which includes a compiler along with some support code for
various editors).
There's been some efforts to extend package.el so it can better handle .el
files in subdirectories, but there's more work to do there.
But normally the way a package is activated by package.el is just by
loading <pkg>-autoloads.el so that can deal just fine with the case
where the .el files are in .../lisp: it's the responsibility of the code
that installs the package to compile the files in .../lisp and to setup
the autoloas in <pkg>-autoloads.el; and the code in <pkg>-autoloads.el
can add the .../lisp dir to load-path rather than the top-level dir.

Sounds like a bug, indeed. Could you M-x report-emacs-bug with a recipe
to reproduce it?

AFAIK package-initialize doesn't update any local metadata.

That's what happens, AFAIK.
