As we discussed https://bugs.python.org/issue35283.
Now is the time to remove Thread.isAlive.
If it is okay, I 'd like to work on this issue.

Calling threading.isAlive() starts to emit a DeprecationWarning in Python 3.8. I'm ok to remove the alias in Python 3.9.

bpo-37804: Remove the deprecated method threading.Thread.isAlive() (GH-15225)

The threading documentation for 3.9 still claims "While they are not listed below, the camelCase names used for some methods and functions in this module in the Python 2.x series are still supported by this module." It would be better to mention when isAlive was removed.
The method is still used in some major libraries, like NLTK (https://github.com/nltk/nltk/blob/637af5380d6071517a5f0d224649e5c3560b5f91/nltk/inference/api.py#L536). Documenting the removal clearly in the threading docs would make it easier for developers to upgrade.

Do you want to propose a PR for that?
I see still 4 camelCase methods in threading.Thread:
JelleZijlstra commentedon Apr 2, 2021
Sure, I can submit a PR. While we're at it, we should probably also deprecate the setter/getter methods that you mention.
Here's what I propose doing:
If there's no objection, I'll open separate issues and PRs for these in a few days.

You can deprecate them. Please open a new issue for that, this one is closed and specific to Thread.isAlive.
