In 1.21.4, MC-152728 was fixed.
This was a terrible change and currently, there is no mod to revert the change.

The mechanic has been in the game for years and now that's gone, it's just terrible to play around.
The option to revert the fix for MC-152728 would be amazing.

This is out of scope for Client Tweaks because it reaches too far into Cheat territory. If anything it would have to be a standalone mod that can be consciously added to a server.
