No mikrotik_hap-ac3-squashfs-sysupgrade-v7.bin?

Hello. Why there is mikrotik_hap-ac3-squashfs-sysupgrade.bin but no mikrotik_hap-ac3-squashfs-sysupgrade-v7.bin file in https://downloads.openwrt.org/releases/25.12.2/targets/ipq40xx/mikrotik/ ?

Just a few days ago I bought hap-ac3 with a sole purpose of running OpenWRT on it but unfortunately it came with RouterOS abomination of version 7 straight out of factory.

Is the absence of -v7 variant just an oversight in build scripts/configuration or is it something more than that?

It appears that the -v7 variants are only those with nor flash, the nand variant doesn't have it defined. No idea why, but here's a starting point for unraveling it:

github.com/openwrt/openwrt

target/linux/ipq40xx/image/mikrotik.mk

main

DTS_DIR := $(DTS_DIR)/qcom

define Device/mikrotik_nor
	DEVICE_VENDOR := MikroTik
	BLOCKSIZE := 64k
	IMAGE_SIZE := 16128k
	KERNEL_NAME := vmlinux
	KERNEL := kernel-bin | append-dtb-elf
	IMAGES = sysupgrade.bin
	IMAGES += sysupgrade-v7.bin
	IMAGE/sysupgrade.bin := append-kernel | yaffs-filesystem -L | \
		pad-to $$$$(BLOCKSIZE) | append-rootfs | pad-rootfs | \
		check-size | append-metadata
	IMAGE/sysupgrade-v7.bin := append-kernel | kernel-pack-npk | \
		yaffs-filesystem -L | pad-to $$$$(BLOCKSIZE) | \
		append-rootfs | pad-rootfs | check-size | append-metadata
endef

define Device/mikrotik_nand
	DEVICE_VENDOR := MikroTik

Could be a hint.

Thanks. hap-ac3 seems to be booting flashed OpenWRT happily even with bootloader from v7 RouterOS.
