Leaves Decay on other Leaves

In vanilla Minecraft, the leaf decay mechanic works in such a way that leaves do not disappear as long as they are connected to either a wood block or any other leaf block. This mod changes these rules - now foliage will disappear if its only connection to the tree is through leaves of another type. For example, when cutting down a birch tree, all its leaves will disappear, and none will remain hanging on oak leaves.

The mod can work exclusively on the server side but also functions perfectly in single player.

Important requirement: MixinBootstrap is required until Forge starts including Mixin as part of its distribution.

Video note: For demonstration purposes, FastLeafDecay was used to speed up leaf disappearance - this mod does NOT accelerate the leaf decay process.
