I am sure it is only a matter of days (hours ?) before Power Query is updated with the Google Analytics connector as well, but I find it very interesting that new Power Query features are now first released in Power BI Designer. I had speculated earlier that Microsoft would/should focus on Designer as the primary means for innovation delivery and perhaps we are witnessing this now.
