I tend to update my Karoo pretty quickly, but I have never seen any indication that it would force an update, so I think people could stick with last week's version for as long as they want.
That being said, this week's update that removed Di2 also added some nice location-based auto lap features, which are way more useful than an icon telling me which gear I'm in, which I already know, so I updated.
