I've been disappointed by the "Python 3 Wall of Superpowers" and the fact that they've basically never updated their package list. (They update the Python 3 readiness, but you'd never find out if a popular package created in the last 4 years was incompatible, or if packages on the list have become unpopular.)
Today I found py3readiness.org, which is much more relevant and up-to-date. It has a better call to action, too.

Thanks for noticing py3readiness.org
Yes, it's up-to-date and takes advantage of https://github.com/brettcannon/caniusepython3
Also, you can help to keep it updated https://github.com/chhantyal/py3readiness
* Python-MySQL is abandoned, but it's been superseded by python-mysql-connector.
* oauth2 is kind of superseded by oauthlib.
* pathtools can probably be replaced with Python 3's pathlib.
* ipaddr can be replaced with iptools, which has the additional advantage that you can contribute to it without approval from Google's lawyers.
In above list, these are not drop-in replacements and it will require lots of changes in your application code if you want to use them. One idea is to show alternative packages https://github.com/chhantyal/py3readiness/issues/9
