Also, if this is all we're after, I'd like to push again for making it
optional - for flit, the resulting wheel will always be the same whether
you copy the files somewhere else first or just build from the original
source tree. It's less to implement and more performant if flit can just
build the wheel directly, and skip the copying step.
