When one does better it usually ends up with some form of tracing GC implementation, as per most CS research papers, it just gets to call it reference counting with optimizations to feel better.

That's definitely true of some enhanced variations on reference counting. The changes I mentioned though do not involve any tracing of live data at runtime. (Although once one introduces the possibility of general cycles, it seems hard to avoid the requirement of tracing some live data.)
