I still don't understand what this means, and why it doesn't choose
one of them arbitrarily.

If you edit your config file to select a primary one, it would work?
If you select the other one as primary, would it still work?

Can you please explain why the OS console device is relevant here? You
said it is not about initialization - I don't quite get it.

Yes, but the same situation could happen on a desktop. Assume I would
have such a machine and boot it with serial console. According to your
logic (as far as I understood it so far), I wouldn't be able to use X.
That sucks and would clearly be a serious regression.

I'm sure I'm missing something, so please give more details.
