Terminology matters. Words mean things. There is no such thing as a "custodial wallet"; that is an "account" you have with a custodian.
When you say "non-custodial wallet" you are playing the tyrant's word games. "Non-custodial" implies that "custodial" is the norm. It is not and never should be.
Because there is no such thing as a "custodial wallet," there can be no such thing as a "non-custodial wallet"; that's just a wallet.
So when someone pays a mining pool out-of-band to prioritize a transaction, the miners contributing to that pool likely never see any of that money because it's not actually part of the transaction's fee, yea?
As a miner, I would not contribute hash to such a pool. I would feel like I was not being compensated fairly.
