we as a network are opening the door and welcoming more spam, in a easier, more harmful in content that will be stored forever because of a spam attack that was a fad that is basically dead already. Core should be the standard of what we as a network (nodes) want and accept, large arbitrary data contents are not desirable, and Core should represent that, even if it happens anyway in a smaller scale, thats the definition of spam, it will always exist, even in Core 30 there is zero guarantees that the same utxo spam will not be done by bad actors.
