The Vasa didn't start out top heavy. Marketing decided they needed new features to keep up with the cutting edge of flagship design.
They were added by reluctant developers while trying to stick within original project schedules and work with a design that wouldn't easily accommodate RFEs. Then marketing added some more. Bigger canons? Yes! More canons? Yes! Another gun deck? Damn right we will!
Familiar, no?
Which is what Stroustrup is warning against.
