They are the perfect tool for the job, recon drones are like classic "Bird Dog" artillery spotter planes except they get tons of bonus points for being unmanned and thus able to constantly bluff lasering a target even when no backup is available anywhere nearby and do it without risking a human life... at which point Ukraine can jump inside the heads of russians to distract, exhaust and channelize their actions for essentially zero cost.

Then when the war finally ends you have a massive stock and production capacity for highly automated unarmed lightweight electric long endurance drones capable of carrying sophisticated sensors on gimbals that are superbly useful for all kinds of peaceful/nonwartime/lifesaving uses and thus the military economy dead end trap is avoided.

The "Albatross Spam" strategy as I call it also gives no effective time for russia to rebuild its relative dominance over Ukraine during a period of peacetime as in contrast russia has put ALL of their eggs in the jet powered flying bomb basket which is a complete dead end during peacetime as they are narrowly useful as still very expensive (much more than your car) murder devices. Thus during peacetime the russian economy as they say in drag/street racing will "get walked" by the Ukrainian economy even as russia goes pedal to the medal itself.
