That was my initial thought as well: this would just become an arms race to submit your trade last? But maybe if the trades were priority queued it would negate that.

Correct. I believe you need to randomize the auction time. This massively reduces the speed advantage. Without that speed is as important as ever.

How does a priority queue work?

[akvadrako]

That just leads to the same question: is there proof its harder to game random batches?

[fighterpilot]

Gameability is distinct to whether there is an advantage to low latency. A random batch auction will be gameable but not so much via speed. Not sure how a math proof would work for that though.

If the trades are priority queued, then you have just recreated the speed "arms race" that this idea hopes to eliminate.

[aserafini]

But if you submit your trade ‘first’ you miss out on any information that arrives afterwards.

Maybe it cancels out the advantage of being ‘first’? I am admittedly well outside my area of expertise.
