[issue43625] CSV has_headers heuristic could be improved

[Łukasz Langa]

Łukasz Langa <lukasz at langa.pl> added the comment:

Since this is a heuristic change, I'm thinking we shouldn't backport this to 3.9. This way it will be easier for application authors to notice the change and control it within their apps.
