I would express all of the concerns being expressed here were debated ad nauseam over the three year political process of getting this proposal accepted. If you want to vent your fears and frustrations in a hopefully more productive way, you can get involved in Python's process.
All that is to say, I'm thankful that the Python community gets things done, and people are willing to go through three year processes for changes such as this.
I also want to highlight these packages will be part of the stdlib for python 3.12, which will EOL in October 2028. In other words, if this change will affect you then you have up to 6.5 years to figure out and implement a plan.
For reference here is the first discussions: https://discuss.python.org/t/pep-594-removing-dead-batteries... and https://mail.python.org/archives/list/python-dev@python.org/...
And nearly 3 years later here is the second discussion: https://discuss.python.org/t/pep-594-take-2-removing-dead-ba...
I thought that feedback from the first discussion was carefully considered and I'm pretty happy with take 2. I have used the some of the modules being removed but largely agree now they are either legacy or there are significantly better third party options.
