While this is a cool project I kinda wondering if they tried submitting a PIP. I think such debugging enhancements to Cpython would be great. Is Python communities considering any improvements on traceback information?
I assume you mean PEP (Python Enhancement Proposal) :)
A PEP has a lot more to consider than a standalone, third-party projects. They also need to support most (of not all) usages of Python, which is extremely involved. E.g. zip import might be a problem, from the top of my head.
It is always worth considering proposing a PEP, of course. But don’t expect people to have interests in proposing, or (if they do propose) the proposal to get anywhere without significant efforts (and compromises).
