so *i'm* not quotes considering it quotes - if it's there and there's a linux kernel module it's there, people can compile it and use it.

Can't use it if the pin has no connection to the CPU!
In the last screenshots I saw ( http://hands.com/~lkcl/eoma/a20_hdmi_review/scrn2.png ), pin 2 HEAC+ (ethernet/ARC) is not connected to anything. Pin 1 (HEAC- & HPD) does go somewhere, but it's of no use for these functions by itself.
CEC does seem to be routed and is mentioned on the A20 info page.
No SBC that I've seen actually uses these functions (unfortunately).

... because the A20 doesn't have anything to connect it to.

I agree, sounds like HEAC (HDMI Ethernet/Audio Return Channel) won't work as we don't have the pair connected to the CPU and that signal is HEC -- differential, ARC -- single-ended.
On the other hand HPD (Hot-Plug Detect) should work.

We'll have to see if we can make it work.
