Useless Lab enchantment: +20% Sweep Knockback Chance

Hi,
just got the enchantment in the title. Since Sweep has 100% knockback chance now that enchantment should be removed, right?

Thanks

This! I was looking through what enchants were available for sweep and realized how annoying it must be to get this one. Perhaps it could be changed to knockback distance or something? Although knockback distance feels quite useless unless they change bleed to do damage per unit travelled or something. Which when thinking about it could make for some fun knockback dist bleed builds.
