No, that is perfectly fine, just that we have more or less GENERIC images,
which arn't announced as such.

There are more confusing things I've noticed.
The PINE64-LTS uses u-boot-sopine, although the u-boot repository has a config
specificly for the PINE64-LTS.
There is a u-boot for OrangePI Plus 2e, but none for the OrangePI Plus 2.
Also the u-bbot git misses a config for the OrangePI Plus 2, but I assume
those boards are identical for the OS as the difference only seem to be that
the Plus 2 has an USB hub and a USB-SATA bridge.
The WiFi chip on the 2 is a smaller package, but both are Realtek RTL8189.
The amount of available Allwinner based boards on the market is irritating
all by itself...

Oh - good to know.
Still have to find out about ZFS root.
