Tracking is behind $VisualEditorTrackBlockNotices config flag which is set to false by default. Additional data will be logged into a different bucket on the client and both metrics will be considered with their known limitations. The reason behind this is to get an idea on how frequently blocked users attempt to edit a page. Similar tracking is being added to MobileFrontend and mediawiki/core.
