The detached-HEAD approach also has the advantage that you don't leave
around stuff (new branch heads) that may have to be cleaned up or
modified in the future.  So you can tell someone about

	git clone git://url/
	git fetch origin
	git checkout <whatever>
	git remote add remotename git://other-url/
	git fetch remotename

and as long as they're not making changes, that's pretty much all
they'll ever need to do to checkout any version.

Sure, you can tell them to reclone every time, but I think they'll get
frustrated with that pretty soon.
