I will keep them here in a list for now for simplicity and edit this issue over time.

• Rename Piwik\Plugin\Segment::setRequiresAtLeastViewAccess to something like setRequiresRegisteredUser or something to make sure what it actually does is hiding it for Anonymous (eg VisitorId, UserId, ...)
• Change Dimension::configureSegments() to Dimension::configureSegments($segmentsList, $dimensionSegmentsFactory) similar to how Report::configureWidgets and WigdetsList works
