Stop and configure mobs despawn

[Robolightning]

A feature that disables the despawn of hostile and neutral mobs (this could be configurable). Preferably in all mods, not just vanilla Minecraft.
I understand that despawning is an optimization, but on powerful computers this should not be a problem and can significantly improve the gaming experience. In addition, peaceful mobs do not despawn at all, and this does not cause any noticeable damage to performance.
I haven't found any similar mods.
The simplest solution would be to add a {PersistenceRequired:1b} tag to all mobs upon spawn, but perhaps there is a better solution. And there may be problems with entities that are supposed to disappear on a timer, such as arrows. And there may be compatibility issues with other mods, I understand that. It would also be cool to be able to configure the maximum number of mobs in a chunk, at which spawning stops, and the speed of spawning itself
