Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

Subject: [PATCH] Make sure inlined getChunkAt has inlined logic for loaded
|
|
chunks
|
|
|
|
Tux did some profiling some time ago and showed that the
|
|
previous getChunkAt method which had inlined logic for loaded
|
|
chunks did get inlined, but the standard CPS.getChunkAt
|
|
method was not inlined.
