It will indeed have to download part of the history to build the
working tree, but the big difference it that it will discard it
instead of storing it locally.

Note that having the history local is a kind of cache, that will make
subsequent operations faster. 'checkout --lightweight' is to be used
mostly when the branch is local (or on the local network for example),
or when you run out of disk space (which is indeed quite unusual on
modern machines. except for very large projects, you don't mind
spending a few megabytes for a cache).

There's a bug open for this in malone already. Yes, this is a problem.
