This mod is designed around Buggi’s multiplayer streams so many of the changes are a result of having 6+ people all needing parts and supplies. The quickaxe is just a result of his hate of grind, plus who wants to watch him his for 40 minutes? College Jacket is because historically vehicles were not reliable on MP servers. Use the WeedCleaver for a little extra boost to farm harvests.
The forum topic of the mod is here.
