The answer is quite simple.

The existing forks don't meet up what we requires, so we made up a small team and created this fork.

As you can see, this fork is designed to be stable and well supported Purpur fork, but it also gain some performance improvements.

The improvements of the API is also being valued, so we will try our best to work on it.
