Let me rephrase my example :

To give one of my project to someone else I have copied it on a USB key.
By a simple drag and drop with the mouse.
And I am quite sure I am not alone doing this way.

I have done those kind of things lot of time without any problem.
But that day 'the_project' happened to be a submodule cloned by
'git submodule update' then on the USB key the $GIT_DIR of 'the_project'
was missing.

If 'man git-submodule' have made me aware of the particularities of submodules
clone I had write in a terminal:

git clone the_project /media/usb/the_project

Or at least I had understand what happened quicker.

I have nothing against also adding something in repository-layout but I am
pretty sure normal users never read repository-layout as it is not a command
they use. And it is not mentioned in most tutorials.
