"Negatively impacts price signaling" is pseudo-economic gibberish. Price discovery means users bid sats for scarce blockspace, and miners include the highest payers. Trying to ban fee-paying demand to protect your subjective idea of "pure" data is central planning.
It’s still total dead weight on chain/nodes.. plus, fees from non-monetary data negatively impact the price signaling feedback loop between fees/rewards, hashrate, and difficulty.
Just because Op_Return doesn’t create extra UTXO bloat on Bitcoin, doesn’t justify its use.
