No Firework Boosting

This mod completely blocks the ability to use fireworks for acceleration when flying with elytra. It's compatible with installation on both the client and server sides of the game.

If you install the mod on the server, all connected players will lose the ability to boost with fireworks — even those who don't have this addon.

When installed on the client, the mod removes the swing animation when activating fireworks during flight. If the server doesn't have the mod, flight with acceleration remains available.
