Bah, I misunderstood you.

Then yes, if all the writers are always in order, and you don't
actually care about exact time matching but only ordering, I guess it
might work.

But since you need all the same barriers that you would need for just
doing it right with a seqcount, it's not much of an advantage, and it
doesn't give you consistency for any other kind of action.
