It's RFC, features are nice to test things and see if/how they work.
Features are not a user option, so you don't have to worry about them.

Also, 'better' is a very hard thing to quantify. Some people like
throughput, some like latency, and others like raw context switch
performance.

Hopefully we'll soon have a non privileged sporadic task scheduler for
all our srt media needs.
