It is good that you are pleased by that, but we tried ath11k, and there are some issues, though. As mentioned earlier.
I can not promise if we will bring all the stories, including technical details about challenges we had with Wi-Fi 6 support. How many cards did we test, why they are not suitable for us and such. I think it would be great, but it will mean that I need to write it first. Maybe later.
But… there is something, which is currently in testing and preliminary result looks good. 
Before we can share it with you guys, there are two issues left:
- https://github.com/openwrt/luci/pull/4994
-
https://git.openwrt.org/?p=project/iwinfo.git;a=commit;h=50b64a63e3945693646d1b2eb4e59e14e35cedc3
(This is not included in any OpenWrt branch, yet.)
However, something is planned on our social media, stay tuned!
