Image Builder does not include tplink_tl-wa901nd-v3

Hello, i have upgraded my tplink_tl-wa901nd-v3 with 8mb flash instead of 4mb,
this model target is tiny (ar71xx / ath79) according:

i am tying to build my own package using image builder with link:
https://downloads.openwrt.org/releases/19.07.9/targets/ar71xx/tiny/openwrt-imagebuilder-19.07.9-ar71xx-tiny.Linux-x86_64.tar.xz
but i found interested thing, there is WA901ND v1/v2/v4/v5 without v3

my question why WA901ND v3 not available while it confirmed (Starting with version 19.07.4 OpenWrt supports these routers with the new target ath79-tiny )

The WA901ND v3 was ported to ath79 in mid-2020, obviously that was too late for the 19.07 release. I believe 19.07 still carries it in the ar71xx/tiny target.
