It's nothing to do with being 'mean and cruel' and everything to do with limitations of technology and optics. When you increase the sensor size you also increase the lens size which means for the same size of package, you can choose between a larger zoom or a smaller zoom/prime and a larger sensor. You can see exactly the same as the
Mavic 2 options in the camera market as well, those cameras offering monster zooms such as Nikon P1000's 125x zoom use tiny 1/2.3in sensors the same as the
Mavic 2 Zoom. Jumping up to the 1in sensor size the same as the
Mavic 2 Pro which is a much bigger sensor, the largest zoom range drops to 25x in the RX10 mkIV. Onto the much bigger APS-C sensor which is popular in the crop Canon, Nikon and Sony DSLRs and the largest zoom range drops down to 17x with the 18-300mm then all the way up to full frame and it drops again to 11x with the 28-300mm superzoom. Not only that when you couple a full frame body onto such a lens, you have a much heftier combo.
I'm impressed DJI managed to squeeze a 1in sensor onto the
Mavic 2 and I think it's extremely unlikely they'll offer a 1in zoom as size and weight are a crucial aspect of a drone, much more so than a handheld camera. And even if they can offer that with a 1in sensor then they could offer a superzoom range for a 1/2.3in sensor.
What seems more likely which I've seen suggested a few times is for DJI to still offer different cameras but make the gimbal and camera a modular design to allow users to purchase one model and then purchase the alternative camera module with the option to easily swap them. This has the further benefit that it would make the gimbal more easily replaceable which would be useful given the delicate gimbal is the part most likely to be damaged when the drone crashes.
Ultimately there's always something better round the corner particularly with technology, you have to assess whether the current product does what you need and weigh that against waiting for a new product which may offer what you want. I would love a Mavic with an APS-C or FF sensor but to put it mildly, that's not going to happen.
