slightly OT but what else is new...
Well the dude above you brought the thread back from the dead so...
I have a fair amount of chain drop on my '90's mountain bike, but nothing on my newer CX bike (knock on wood). To a large degree the derailer acts as a chain retentioner (which is why a lot of 1x setups put a chain retentioner in place of the derailer).
With a short cage rear, proper chain length, and correct derailer limits it shouldn't be an issue. Ya can always use a clutch rear derailer if you are worried.
That said, I'm in my small chain ring for CX races. My speed is typically in the 10-12mph range so I don't need a big ring for that. I do hit it hard when we jump onto the velodrome on the CX race, but that isn't much over 20mph. Any time I might be able to use a big chain ring in a CX race, I'm letting my heart rate relax before the next climb/run...
