Are there any plans to make a client side version for this changing how packets, hitboxes work and how hits feel? Along with movement revert-backs? (There are more changes but u get the point)

The goal of this mod isn't to restore 1.8 PvP exactly as it was but rather to bring it to modern versions. I personally don't see the point in changing such minor details as the hitbox size, and I don't think it majorly affects how the combat works, nor do I have the time to track and implement every small change that could affect combat since 1.8. I also don't want to get rid of the advantage of not having to install it on the client if used on a server.
