I think this would be somewhat confusing. I know that the statement is strictly logically correct with "unpacked", but it seems as though it would imply to many readers that the package is *only* unpacked, not also configured. In the absence of dependency loops, Depends should guarantee that the depended-upon package is configured rather than merely unpacked while the depending package's postinst runs; I'm not sure about prerm and postrm. I feel that this may be too fine a distinction to draw in this paragraph without being confusing, and it would be better left non-specific.
