I'm just a civilian, but from playing enough strategy games, here's maybe a dumb take: Crimea is easy to attack - in range, and they have good enough intel. Assuming they're not wasting rare ammo on the attacks, continuing to degrade air cover makes sense, since Russia cannot give up on having coverage, since if it really goes away, Ukraine might be tempted to follow-up.
If they nowadays mostly waste domestically-produced drones, then it's as good as using them deep in Russia, plus Crime's sentimental value for Russia.
