Agreed that this is not ideal and its a risk on bitcoin stability (assuming the BIP-110 fork is initially a minority chain), but in your opinion, what should we do about UTXO bloat (which is a risk on decentralization) ?
I think putting a hard cap on OP_RETURNs would be the single best non-risky thing to do. However, I think bitcoin adoption will cause blocks to be mostly full a few years from now - and the fees to be much higher. So it would only buy some time & avoid harmful content onchain.
That being said the cost of storage keeps getting lower and lower, but bitcoin block size is static, so all things consider it should only get easier to run nodes from now on.
