Which transactions get into which blocks when doesn't require a hard fork. Coinjoins are already a thing on Bitcoin.

Actually there already is a precedent for this: Miners include transactions with the highest fee before they include the oldest transactions.

I don't know the tradeoffs but I'm also not advocating for a hard fork. Other than requiring consensus changes (which is a massive downside on its own), there are undoubtably huge tradeoffs - in UX, security, etc. e.g. Mimble Wimble Coin had a huge DoS vulnerability in its implementation.

I'd argue that bigger coinjoins transactions are simpler and more elegant for a base layer?

Do we need protocol level Coinjoin?

What would be the tradeoff?
