BTW, I notice that a lot of text is getting removed from commit messages when PR commits come on to main. For example, the commit message of the single commit for this PR was:

Revert previous "precommit autoupdate (#3214)" commit; it's broken

The top-level linter setting names in pyproject.toml have changed, and
while this _could_ accept the old names until they're fixed, it choses not
to and fails the build.

Fixing that is easy, but results in yet more failures that were not
previously appearing in unchanged code.

- Revert "[pre-commit.ci] pre-commit autoupdate (#3214)"
- This reverts commit 3347933a4e3d5cda8f993ffccc3f79b5a01a819c.

But in the commit that was actually put on main, it's just:

Revert previous "precommit autoupdate (#3214)" commit; it's broken (#3215)

I've seen similar in other PRs.

The original commit messages do still seem to remain available if you come back to the PR, but I suspect that they may disappear if I ever delete my fork repo containing the dev branch.

It's up to you, of course, but it might be worth keeping the full commit messages on the main branch as well, rather than trimming them.
