All of the important events that would fire with great frequency on a large save, like on_entity_died, supports filters to improve performance. On_tower_mined_plant is an exception, and this makes certain optimizations I would like to make impossible. On a large save with many agriculture towers from several different planet mods, any script that only targets one plant type would fire on every agriculture tower at all times.

I’m not against adding filters however I think you’re drastically over estimating the frequency that event happens. Outside of an artificial test case - and even in one - I have extreme doubts you’d ever see a performance difference with vs without filters.
