Calling it "stupid" isn't a great way to get a useful discussion.

I would say that alacarte has been buggy for the better part of a
decade, and you're only now getting an actual error. Here's the change
- it wasn't a rename at all:

https://docs.python.org/3/whatsnew/3.9.html#you-should-check-for-deprecationwarning-in-your-code

The "collections.Sequence" alias has been kept for backward
compatibility, but as of 3.10, has been removed. The correct spelling,
"collections.abc.Sequence", has been valid since at least 2012 (that's
when it started emitting a warning - don't know if it was available
longer and I don't have a Python 3.2 to test). So either alacarte
hasn't been updated in many many years, or nobody has bothered to
check the warnings.

Maybe, rather than calling the Python devs "stupid", you should
consider sending pull requests to projects you use, fixing things that
are raising warnings?
