My current understanding of the blockchain builder and bundle system is: don't think of yourself as a naive retail investor who just "submits and gets into the block"... You're running naked in the mempool, encountering front-running or queue-jumping is very normal. How much do you need to know? I think three points are enough: 1) For large or sensitive operations, try to use private channels (don't broadcast publicly); 2) Don't swap, borrow, and open positions all in the same transaction, avoid giving others a package deal; 3) If the transaction looks suspicious, first suspect the execution path, don't just blame your slow hands. As for further research into builder ecosystems and bidding rules, honestly, like going to work, I’m not too interested unless I can also earn mileage. Recently, the "yield stacking" of staking and shared security has been criticized as repetitive, but it's similar: the more layers there are, the longer the chain, and you might not even see who’s inserting themselves in the middle. If I had split a bunch of aggregated transactions earlier, I probably would have paid less tuition... Anyway, if it can be automated, do it automatically; if not, don’t do it.
