We can get rid of it in Drupal 10 ;) Should we include our own deprecation here of the old interfaces that we exposed, targeting Drupal 10?

Removing this in Drupal 10 would mean that we would also have to remove PHP 7.4 support. We'll have to refactor the methods into new ones and then deprecate existing methods. But that would be tricky too as these are actually concrete methods in \PDOStatement and we extend that class.
