The reason is that `append_crate` has lost its `is_workspace_member`
parameter, so the only way to pass `False` now is to use
`build_crate`. I chose to remove the argument from `append_crate`
because the alternative would have introduced many instances of
`is_workspace_member=True`, which I judged to be less-good than this.

Cheers.
