I wouldn't consider these mistakes or omissions. He's reviewing the board as is and not assuming future progress that may or may not take place in some undetermined time. If I'm looking for a relatively cheep single board computer to play with and am not focused on specific RISC-V development I want to buy a board for what it can do now not what it will be able to do with kernel updates that are not guaranteed.

Then buy something else.
My VF2 boards (one 8 GB and one 4 GB) were very clearly sold as "Early Bird" and "Super Early Bird", respectively, and Jeff's will have been too.
They are for early adopters and for developers to use to fill in the missing software support. It is not practically possible to do this without a board in your hands.
It is NOT for the average user right now. In 3 or 6 months it will be.
