Wow.. good job! Of course they have to use a non-standard implementation of everything. |

That is the (former) official Java implementation of LZ4. So not really a decision from Mojang. The code implies that nowadays you should use LZ4Frame format, but the used format is something legacy that works only for the Java version. |
uncompressed means that we can just copy the NBT data

With Minecraft version 24w04a Chunks can also be compressed with LZ4 format.
Even some longer time ago it was introduced to store Chunks completely uncompressed (according Wiki since 1.15.1).
To test this feature yourself, start a new test world and edit server.properties before exploring. Chunks will then be stored according to your configuration.
This PR adds support for these storage modes:
Furthermore the rest of the code is refactored to remove all code duplication and use the same methods for all compression methods where possible.
