For someone who went for the trouble of buying a dedicated mirrorless lens, let alone a full frame one, a superzoom is unlikely to remain the only lens. I can envision using a superzoom lens when shooting a critical assignment when an all in one lens is required to minimize switching time, maybe a warzone in a desert... (however, lately I've become too fond of two-body shooting that might be an alternative option for such a predicament). Or, scratch that, shooting a Soyuz space capsule descent when you need to get lots of shots with various framing but absolutely cannot waste the time swapping lenses, and don't even have the space to do this inside a cramped helicopter with only one open door (a colleague who was doing this sort of shooting a few times described the process once; it really is rushed and free space is nonexistent).
For (leisurely) travel, ironically, I find the combo of 16-35 and 70-300 lenses works best. You don't want to compromise on quality too much if you're visiting a destination you're only going to see once in your life...
