Couldn’t censoring by proposers be much more subtle and efficient than this rather blunt instrument? For example, a proposer could easily hold a business to ransom by selectively filtering transactions to its contracts. The proposer needn’t even lose out on Tx fees if there are alternative Txs it could include instead (to address the later point). DoS attacks are a thing, and it would be a shame to make it easy. The company’s defence is to spin up its own subsidised proposer to rescue its Txs, or tell its users to use higher fees, and escalate from there… Anyway, it seems undesirable.
Which means that, in this stateless client regime, self-proposals become the dominant strategy. QED.
Yep, will be taking a look at it.
