I think that when you already have opencv+qt5+opencv installed, an automatic upgrade to opencv should behave like `port upgrade opencv`. IOW, it should maintain the active variants. Anything else is a waste of time and source of frustration.

And neither do I see any reason why the use of the active_variants portgroup would change anything in this matter, but one can never be too sure.

Let's see what Marko has to tell us about the exact command he used that led to opencv being upgraded without its current variants.
