I don't think the behavior is intentional, but a side effect of the
fact that git takes some shortcuts when cloning locally. In particular,
it will try to copy or hardlink the object database rather than
transmitting over the git protocol locally. Using file:// has always
been the way to suppress that shortcut.
Perhaps to avoid surprise, that optimization should be turned off for
options which cause it to behave differently (like --depth). But I have
to wonder what the point of --depth is locally; if you are worried about
space, hardlinks (the default) or alternates ("clone -s") are a better
solution.
