 progenitors had use_count(), and it was useful in tracking down bugs in a
 complex project that turned out to have cyclic-dependencies.</p>

+<b>A.</b> Because complexity limit implementors and complicate the specification without apparent benefit to

+<b>A.</b> Because (your pet feature here) would mandate a reference counted (or a link-list, or ...) implementation. This is not the intent.
