another benefit would be that the combat would be more challenging but not too challenging if you're ready , in my experience mobs are one hit away from death from a power V flame bow , the game will generally just be more interesting in my opinion , downsides would be with new players , they could die with starvation but that can be solved with /kit ot most town warps , zombies can knock down doors but that can also be resolved with lighting your area , so i see that the only problem i see without an easy solution is that mobs will be stronger which might be harder for new players , but i think it's part of the fun when you're new trying to survive mobs and hiding in holes , first time i played minecraft i hid for the whole night when i saw an enderman , so i think it will generally be more beneficial for the community
