Would probably also be a good idea to update the advice in https://docs.python.org/3/whatsnew/3.11.html?highlight=getfullargspec#removed so it no longer recommends getfullargspec:

The getargspec() function, deprecated since Python 3.0; use inspect.signature() or inspect.getfullargspec() instead.

@hugovk Thanks! This would need a separate PR.

What's the reason to use the minimum length of the deprecation period?

No real reason, I think that the transition will be rather smooth, considering the existance of https://github.com/wemake-services/inspect313

But, we can set any remove= version, this is not really a problem :)

This PR is stale because it has been open for 30 days with no activity.

@sobolevn: This change is now outdated since it refers to Python 3.13. Do you still plan to work on this PR? If not, I suggest closing it.
