It depends. If you start a war with a reasonable stockpile of artillery and shells then you will have a greater amount of shells than firing pieces at the start. So you can fire with your guns but you can get a big advantage if you can fire more than your opponent in the first round of fire and in the first few days. So if you can have a bunch of these cheapo things then you could effectively double or triple your rate of fire for a short period. That can be a big advantage if it means you break through fortifications or disabled anti air defense. They can move faster and be more responsive than moving artillery pieces around especially in rough terrain.
So you want both really. Having more options is better.
these things are so slow to drop 1 bomb its not increasing rate of fire at all. Their only advantage is that they dont get hit by counter artillery and dont require an artillery division to operate. It works for ukraine because they cant call for firesupport on most of their fronts.
