It's the difference between peacetime preparation and wartime expediency. If the Ukrainians were able to spend the time and money to move the drone supply chain home, improve sensors, implement electronic warfare workarounds, etc they absolutely would. But right now there are Ukrainians losing hands disassembling conventional warheads to mount on FPV drones because they are needed right now on the front in the fight for the nation.
