The PEP 620 only mentions replacing CPython GC with a tracing GC at one place: "It becomes possible to experiment with more advanced optimizations in CPython than just micro-optimizations. For example, tagged pointers, and replace the garbage collector with a tracing garbage collector which can move objects." I chose to not make it a requirement of the PEP 620 on purpose. IMHO such a change will very likely require a whole PEP by itself, since there are likely many small things which will have to be changed to prepare such a major change.
