> arent nodes running filters to impede this propagation as a way to marginally discourage behavior of relaying transactions not accepted by the wider network? thats the entire point, it works. why wouldnt expanding those filters to include utxo-bloat spam work also? I don't understand why you are saying this works. Clearly transactions are finding their way to miners over the regular p2p network. For what it's worth I also don't understand why this change is sold as company x needs this to post the data as op_returns. They should just do it now, because enough nodes and miners have these liberal policies already. Bitcoin Core should still adopt the relaxed policy to make relay smooth, and make it easier to use, because it reduces harm in terms of node storage requirements, but keep the option, so node runners like yourself can encourage building templates with non-data carrying transactions.
