Asus TUF Gaming AX6000 support

Hi,
I just wanted to post that the documentation here and on

was really helpful. I just flashed my Asus TUF AX6000 and the device seems operational. Thanks to all the contributors.
I also have an Asus TUF BE3600 which I would like to migrate to openwrt.
If I am not mistaken this device is not supported. Is there a known reason why this isn't supported? Would it technically be possible to put openwrt on it?
How feasible is it for me to contribute (a software developer)? Where do I start if I want to have a try?
