Moving equipment like fighters and bombers out of range of drones achieves a significant tactical victory for Ukraine by reducing loiter time at target for Russian aircraft. Incremental losses of both aircraft and crew also have compounding effects, since pilots for logistics roles like in air refuelling become scarce.
I agree that lack of weapons for direct assault limits some of the upside benefits as in "you cannot directly win a war on defensive moves" but you can force a better, safer, more advantageous outcome. In effect, Russia is losing a war of attrition on it's economy and materiel side. It does have massive manpower and stocks. It doesn't have infinite supply of economic resilience and home front tolerance for a failing economy undermines Kremlin myths.
Sometimes, not losing is the best you can get pending more help.
