Vmaf: it is a type of license (still Open) called: BSD + patent:
https://github.com/Netflix/vmaf/blob/master/LICENSE

Instead Av1an is completely Open: GPL 3:
https://github.com/master-of-zen/Av1an/blob/master/LICENSE.md

It would be good to have a new encoder for AV1, because the standard is quite slow. I don't think it's easy to implement it, though?

EDIT:

It seems that the ffmpeg provided by Arch linux already implements vmaf.

I read some of the information, but I could not find anything that said that:

By the way, av1an also uses an algorithm developed by Netflix. It is already included in ffmpeg, but you have to enable it.

was OpenSource. Usually when ffmpeg requires enabling something, it means that it is not open.

Another encoder for AV1, but not only. It has many features including multithreading, which is one of the biggest problems of AV1. It looks very interesting:
