Never got popular enough to be ported to cpython, let alone python 3.
It's no surprise though: my experience is that most python devs don't know how to use a debugger. In fact, the huge majority of tutorials to learn python don't include one, nor they give explanation about python -m, venv, pip, the python path and other very important basis.
Even the people using pdb don't know very important commands like until, jump, up or tbreak.
