Yes.  I think this is what you started to get the ball rolling.
Together with what already diagnoses, I think we can
get a guideline that is more or less reasonable.

This, too.  Running (possibly combined with a bit of
tweaking it to match our needs) already catches many of the issues,
so a tool with a similar interface would be easy to use, I would

I suspect I am discussing this based on a different assumption.

I think the primary goal of this effort is to make it easier to
cleanse the new patches that appear on the list of trivial style
issues, so that contributors and reviewers do not have to spend
bandwidth and brain cycles during the review.  And I have been
assuming that we can do so even without waiting for a "tree wide"
code churn on existing code to complete.
