I don't think orphaning a block here and there matters to this. For the most part every TX that got orphaned will be in the next 2-3 blocks, they are still high fee and in someone's mempool.
The tech seems clear to me, the knots people are somehow more worried about spam in mempool than saved on chain.
If it is just about attitude, this is the guy here to save you from the core team being condescending instead of helping explain the change to node runners.
