Ah, this.
No, it won't.  Your pack files are not transferred directly as Git wire
protocol operates on abstract histories, like "hey, the user told me
to fetch branch «foo», and that has XYZ as its tip commit; let's figure
out which graph of objects you need to pack for me to fetch so that my
«foo» looks like yours".

It also helps keeping in mind that "remote" repositories, even bare,
are not treated by Git in any special way compared to "local": you can
fetch into a "remote" repository, and push from it in the same way you
do in a "local" repository.
