AX1800 QSDK and vanilla OpenWrt

Hello, AX1800 have IPQ6000 used old QSDK too like B-1300 and others?
Gl firmware based on OpenWrt v. 15 with kernel v. 4?
Which is the future of this device in vanilla OpenWrt?

Seem openwrt does not support IPQ6000 yet.

What you think about first two questions?

It is yes for both questions.
