Looks good, except that your proposed qIntrusiveDetached()

The problem with shared_ptr::unique() is weak_ptr: weak_ptr::lock() can
materialize new strong references at any time, cf. wg21.link/P1116 for a
possible solution (which, however, isn't implementable in an
ABI-compatible fashion on most platforms).
QISP doesn't have an associated weak_ptr.
Thanks,
