Pehkui Hurts
by 0P_0PTIC
Pehkui Hurts adds collision damage between mobs whose sizes differ, using the scale values set by the Pehkui library.
What it does
When two mobs touch, the game compares their scale. The larger mob moving into a smaller one deals damage, but only when the larger mob is at least 4 times the scale of the smaller one, and the difference is capped at 100 times. A random variance is added to the difference, so identical sizes still produce different results across encounters.
Players are given a random size when they first spawn, which then feeds into the same collision logic. Both the collision damage and the random sizing are enabled by default, and an optional toggle can turn either or both off. The range of the random size is set in a config file, so server owners can adjust it to suit their worlds.
Pehkui is required and must be installed alongside the mod. A server running it needs every connecting player to have it too. Files are published for Forge only, for six game versions 1.20.1 – 1.20.6, and the license is All rights reserved, so the mod is not open source. Only the 1.20.1 build has been checked by its maker, and that test used Pehkui 3.8.2.

What the author says
Update: - Players are now given a random size on first spawn. - Optional toggle to turn on and off both the collision logic and random size. Both are on by default. - Can coustomize each randomly picked size in config file. I've only tested it on 1.20.1 with pehkui 3.8.2, but it should work on other versions.
