As discussed in #5418 (comment); Clippy's current understanding of cognitive complexity is not good enough yet at analyzing code for understandability to have this lint be enabled by default.

changelog: Remove cognitive_complexity from default set of enabled lints

Wow, you're so fast! ✨

I came here to comment on this little thing, because in my original comment I was definitely a bit ambiguous:

Clippy's current understanding of cognitive complexity is not good enough yet

I'm guessing this comes from me at #5418:

we're not good enough yet at analyzing code for understandability.

Sorry for being so unclear!

I meant we as in, the computer science and software development community. We just don't know how to properly quantify cognitive complexity (in the conversation quoted at #5418 I went into more detail). That's why no tools, not even Clippy, are able to give a satisfying, or generally useful, answer to the question of "Is this function/file/impl too complex?"

🔒 Merge conflict

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.

How do I rebase?

Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:

  1. git checkout cognitive (switch to your branch)
  2. git fetch upstream master (retrieve the latest master)
  3. git rebase upstream/master -p (rebase on top of it)
  4. Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
  5. git push self cognitive --force-with-lease (update this PR)

You may also read Git Rebasing to Resolve Conflicts by Drew Blessing for a short tutorial.

Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.

Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.

Remove lines allowing clippy cognitive complexity checks.

Since these allow lines were added, this clippy lint has been downgraded
to a nursery check via
rust-lang/rust-clippy#5428

Since we don't have allows for other nursery lints, I suggest we remove
these ones.
