It's also potentially risky. What if a big mining pool, upon noticing the huge fee mined by another miner/pool, decides not to mine on top of that block, but in competition with that block in hope of snagging the fee for itself?

There's been a lot of talk about reorg due to MEV (which this could be considered MEV), but to the best of my knowledge it hasn't happened yet. This seems like a big opportunity because this is ~3000x bigger than the standard block reward

We need Ethereum to always prevent this. Or the big mining pool will just do this for every block and allow ONLY THEIR blocks to be processed. Then they get 100% of mining of the ETH mining fees.

This reinforces by most miners being willing to join, to get a share in monopoly rents over miners-never-earning. The big mining pool(s) could let in enough to stay big enough. But not too many to spread the monopolistic gains by too broad a base.

The mining pool would have to have >50% of the hashrate to pull that off indefinitely.
